I. GENERAL INFORMATION
Engineering is a great profession. There is the fascination of watching a figment of the imagination emerge through the aid of science to a plan on paper. Then it moves to realization in stone or metal or energy. … Then it elevates the standards of living and adds to the comforts of life. That is the engineer’s high privilege. To the engineer falls the job of clothing the bare bones of science with life, comfort, and hope.
(Herbert HOOVER, US President, 1929-1933)
„Engineering is a great profession” – said knowingly the former US President in 1929-1933 – the Great Depression period. “The country can not raise but through engineers’ said in the same contextthe famous prime minister, one of the founders of modern Romanian state, I. C. BRATIANU. There are undeniable truths, especially in this period extremely uncertain when humanity faces the biggest global problems – compromising the environment, depletion of energy resources and materials, feeding a growing number of the population. These problems can be solved only by engineers.
The subjects taught within the Department Basics of Machinery Projecting make the foundations of mechanical engineer training. Therefore it is absolutely necessary to perform the structural and content optimization of the taught courses offered to improve engineering training according to the requirements of the future. This became possible due to the formation of Department of Basics of Machinery Projecting on the base of departments „Theory of machines and machine elements”, „Strength of Materials” and„Study and Materials Technology”. The three departments were founded in 1964 when half a century ago came into existence the first institution of higher technical education in the republic – Chisinau Polytechnic Institute. Based on the Order of the Rector nr. 774-r of 05/07/2012 after merging of the three departments mentioned above,there was founded Department of Basics of Machinery Projecting. In 2014 through the restructurings carried out at the university by creating the Faculty of Mechanical and Industrial Engineering, and Transportationon on the basis of faculties „Engineering and Management in Machine Building” and „Mechanical Engineering and Transport”, by Order of the Rector nr.390-r of 07/07/2014, on the basis of Departments of Basics of Machinery Projecting and „Study and Materials Technology” there was created the Department of of Basics of Machinery Projecting. The figure below presents the organizational structure of the Department.
Department of Machine Elements and Lifting-Transportation Installations was created on 1 September 1964 and provide teaching the course “Theory of mechanisms and machines”. Teaching disciplines “Machine Elements” and “lifting and transportation machinery” began in 1965 and respectively 1966. History of the Department and primarily the development of didactic and scientific activity during this half of the century has been marked by a series of events that have influenced the overall work of the Department. The first head of the department was assoc. prof., dr. Ivan BANCALIUC (1964-1965), followed by assoc. prof., dr. Alexandr PERSIANOV (1965). Among the first teachers hired by at the Department were Vasile LUCA, Nicolae MINAEV, Tatiana DIOMINA, Marc ROZENBERG and others. But the founder of the Department rightfully, is considered assoc. Prof., PhD. Glusco Constantin, who was at the head of the Department for the period 1965-1975 (in 1967 was appointed as dean of the Faculty of Mechanics). During this period at the Department were invited young specialists: Victor MUDREAC, Sergiu MACARISIN, Vasile AJDER, Ion TOFAN, Ion COSNICEANU, Vasile COMENDANT, Nicolae BALABAN, Vladimir GUSAN, Galina ROSCA, Ion BOSTAN, Gheorghe POPOVICI, Gheorghe RUDIC and others. Later, as Head of Department is elected assoc. prof., dr. (later prof.dr.hab.) Victor MUDREAC (1975-1985), who renames the Department from Machine parts and Lifting Machines into Theory of mechanisms and machines elements. During this period to the Department came a new experienced staff: doctor of technical sciences, senior researcher, Zaharia DONTU, but also young professionals, graduates of the Department: Anatol OPREA, Anatol LISNIC, Gheorghe POSTARU, Victor CEBAN, Valeriu Dulgheru. In the next five years from 1985 as Head of Department was elected dr., Assoc. Prof. Vasile AJDER. In 1990 the head of the Department is elected univ. prof., dr. hab. Ion Bostan (1990-1995). In 1990 it is formed a new department – the design and manufacture of agricultural machinery, where are transferred dr., Assoc. Prof. Vasile AJDER (as Head of Department), Dr., Associate Professor. Ion TOFAN and senior lecturer Alexei Corcimari. In 1993 the Branch of Applied Mechanics is separated from the Department of Strength of Materials and Applied Mechanics and is included in the Department of Theory of mechanisms and machines elements. In time, the name, structure and composition of the Department suffered further changes reflected in Table 1.1.

The PhD students Ion COZMA, Vitalie GLADAS, Ion RABEI are in the II yearof doctoral studies, and Gavril PORCESCU – in the I year.
Provision with didactic materials of the disciplines taught at the department has always been in the focus of the Department leadership and teachers. Because until 1989 (with some interruptions) teaching of the disciplines at the Department was performed only in Russian, students were recommended textbooks drafted by known teachers in the area from Moscow (D.N. RESETOV, M.N. IVANOV (MVTU “N. Bauman”); C.I. ZABLONSKI (Odessa Polytechnic Institute) and others – “Machine Parts”; I.I. ARTOBOLEVSKI later – K.V. Frolov (MVTU “N. Bauman”) – “theory of Mechanisms and machines”). After 1974, teaching in Romanian was suspended. It was returned to teaching in Romanian language only in 1989, after which there were translated and elaborated all the manuals and tutorials necessary to ensure the teaching disciplines.
The Department “Strength of Materials” was founded in the time of opening the Polytechnic Institute with a number of 7 didactic units. The first collaborators of the Department were: Associate Professor., Dr.in Physico-mathematical Sc., David SILCRUT; assoc. prof., Dr. in Technical Sc., Vasile KLIMANOV; senior lecturers: Victor ANDREEV, Nichifor BARSAN, Petru NICORICI, assistants: Condrea MURSA, Camila POLUSCHINA. The Department had and 4 PhD students (scientific coordinator: assoc. prof., dr., D. SILCRUT): B. PAHOMOV, Iu. BARLADEANU, I. GHERLACU, V. MORAR. During the first two years the post of head of the Department was vacant. The function of head of the department until 1966 was complemented by dr., assoc.prof., David SILCRUT (see Table 1.2). Under his leadership, they were founded and endowed with equipment the laboratories of photoelasticity and mechanical tests. In October 1966 as Head of Department was elected assoc. prof., Dr., Gheorghe MAHO, invited from the Institute of Radioelectronics and Mining Electromechanics from Moscow, who greatly contributed to the development of the Department and endowing it with laboratory equipment. At the Department were invited young engineers from machine-building enterprises: Alexandru HAGIOGLU, Mihai PASA, Stefan PROFIR. In the years 1965-1971 was passed to the Romanian language teaching of general subjects (including “Strength of Materials”). Prof. Gh. MAHO has initiated the teaching of discipline “Strength of Materials” in Romanian. Together with prof. P. NICORICI, A. HAGIOGLU and V. HAGIOGLU he translated the manual “Strength of Materials” (author – V. I. FEDOSEEV) and “Collection of problems”, edited by V. K. KACIURIN (translators: Gh. MAHO, P. NICORICI and A. HAGIOGLU). After 1974, teaching in Romanian was suspended. It was returned to teaching in Romanian language only in 1989.

|1990 – 1994||Strength of Materials and Applied Mechanics||Assoc. prof., dr. Alexandru CRĂCIUN|
|1995 – 2012||Strength of Materials||Prof., dr. hab. Vasile MARINA|
From 1966 the disciplines “Strength of Materials” and “Elasticity Theory” taught at the Faculty of Constructions were taken by specialized departments of the faculties. In 1970, at the specialties with a reduced number of hours (technology, energetic, economic – engineering) the disciplines “Theoretical Mechanics” and “Strength of materials” were merged into a discipline with the common name “Applied mechanics”. In the period 1968-1970 the position of Interim Head of Department was occupied by dr., Assoc. Prof. B. CEAICOVSCHI, who in 1970 was elected by contest, a function held until 1979. In this period at the Department were employed young teachers: Alexei TOCA, Valentin CAINAREAN, Gheorghe TIHENICHI, Veaceslav MAJERU, Ion PARTAC, Valeriu CERTAN. In 1979 as Head The department was elected dr., Assoc.prof., Rix BOGATARIOV (Invited from the Institute for Research in Wood Industry). In this period to the Department came young teachers – Ilie COANDA, Victor BALAN and others. Some teachers were selected as invited lecturers in some African countries: Ion COSNICEANU and Gheorghe TIHENICHI – in Algeria; Condrea MURSA – in Madagascar.
In the years 1980-1990 the reorganization of the departments affected also The Department of Strength of Materials. As a result, there was created The Department of Applied Mechanics headed consecutively by dr. hab., prof. Vasile CALMUTCHI and dr.,assoc. prof., Alexandru CRACIUN. Initially, the department was located in the Faculty of Energetics, then – in the Faculty of Radioelectronics. In 1990 The Department was disbanded and the staff transferred to The Department of Strength of Materials. In the years 1990-1994 Department of Strength of Materials and Applied Mechanics was headed by dr., Assoc. prof., Alexandru CRACIUN. In the academic year 1994-1995 Department was merged provisionally with Department of Structural Mechanics from The Faculty of Constructions. From 1995 until 2012, when it was merged with the Department of Theory of Mechanisms and Machinery, the Department was headed by prof. Dr., Vasile MARINA, and in time, it was completed with young specialists: Mihai VARLAN, Viorica MARINA and Natalia SVEATENCO, the last two have defended their PhD theses under the leadership of prof. V. MARINA.
After merging the two departments – Theory of mechanisms and machines and Strength of Materials, in 2012, a new department appeared – The Basic of machinery projecting, consisting of 19 teachers (half of them – young specialists aged under 40 years) and 4 engineers – auxiliary staff. This consolidation has allowed a better coordination of the disciplines “Strength of Materials” and ” Basic of machinery projecting ” taught within the same departments.
The department “Study and Technology of Materials” was founded in 1964 as part of the engineering Department (TCM), headed by the senior lecturer Oledii DERID, and 1965, after the division there were formed two separate departments – Machine Building Technology and Technology of materials (head The department – Oledii DERID,, senior lecturer). In September 1975 the department was renamed, up to 2014 being called Study and Technology of materials. Lecturers of the basic disciplines – “Study of metals”, “study of materials”, “Technology of materials”, “Technology of building materials” were among the first teachers hired to the Polytechnic Institute from Chisinau. Over the years the Department was headed by doctors of science (see Table 1.3).
|YEARS||NAME OF DEPARTAMENT||HEAD OF DEPARTAMENT|
|1964 – 1975||Study and technology of Materials||Assoc. prof., dr. Oledii DERID|
|1975 – 1980||Study and technology of Materials||Assoc. prof., dr. Valeriu ŞAUGA|
|1980 – 1996||Study and technology of Materials||Assoc. prof., dr. Alexandru CHETRARU|
|1996 – 2005||Study and technology of Materials||Assoc. prof., dr. POSTOLACHE|
|2005 – 2014||Study and technology of Materials||Assoc. prof., dr. Iurie CIOFU|
The first professors of the Department were: O. DERID (Head of the department, Senior Lecturer), I. MURASOV (Associate Professor, dr. in tehn.sc.), N. MARGINA (Senior Lecturer), V. BOBROV (Senior Lecturer), V. MUNTEANU (assistant). Within the Department commenced their activities many teachers, who later were promoted to other departments – assoc. prof., doctors of technical sciences A. CIOBANU, V. ENE, I. RUSICA, V. GOIAN and others.
The Department nucleus became the teachers trained in its „womb”, who have passed here all ranks of scientific and pedagogical training, activating over 25 years – assoc. prof., doctors of technical sciences O. DERID, A. STANCIU, I. VEREBCIANU, V. CUCONESCU, GR. DANTU, V. SAUGA, A. CHETRARU, V. CAZAC, P. POSTOLACHE, Iu. CIOFU, Iu. SOLPAN. In various years in the Department have taught V. Murzac, Gh. Tonu, N. Cibotaru and others.
Currently at the newly formed Department activates the teaching staff, as follows: assoc.prof., dr. Iu. CIOFU (chief of the Program); int. univ. prof., dr. V. SAUGA; dr., assoc.prof. N. TRIFAN, senior lecturer A. IANACHEVICI, univ. lecturer N. KAZAK. The cumulards: sen. lect. A. RUSU, univ. lect. Iu. BARCA. Up to 2005 among the teaches of the department activated the assoc.prof., dr. O. DERID (1925 y.b.). In the years 1985-2000 CSTM was the only department in the university, where all teachers had the degree of PhDs in science.
The Department permanently maintained a high level of systematic professional improvement of the teachers. Internships are performed in leading institutions in the USSR (Moscow, Leningrad, Kiev, Minsk), Romania (Bucharest, Iasi), Republic of Croatia (Zagreb). But in the recent years the improvements outside Moldova, with funding from the budget, have become practically impossible because of state funding stopping the university activities of this kind.
Collaborators of the department are coauthors to three scientific monographs (SAUGA V., Iu. SOLPAN) and possess of rank exhibitions international scientific distinctions (N. TRIFAN), owners of several patents. The Department staff published a total of over 400 scientific and methodical works, has participated in dozens of national and international events (conferences, seminars, exhibitions, etc.).
As a result for restructuring completed in 2014 it was created the Department of Bases of Machinery Projecting, on the basis of departments Bases of machine projecting (in which latle were merged departments Theory of mechanisms and machines and Strength of Materials) and Study and Technology of materials. The structural diagram of the Department, changed in time, is shown in the figure below.
II. DIDACTIC-METHODICAL ACTIVITY
Didactic-methodical activity of the Department is oriented towards machinery projecting needs and is focused on three programs of study: Theory of Machines, Machine Elements and Mechatronics; Strength of Materials ; Study and Technology of Materials.
The program of studies “Theory of machines, machine parts and mechatronics” ensures teaching process on the following subjects within 4 faculties:
- Theory of mechanisms and machines (reissued in Romanian 1 manual, 1 manual translated and elaborated 1 guide book for projecting);
- Bases of of machine projecting (6 manuals were elaborated, 1 guide book for projecting);
- Mechanical Engineering (1 textbook was elaborated and 2 guide books for projecting);
- The principles of engineering creation, technical Creativity (5 textbooks were elaborated);
- Graphical fundamentals of projecting (1 initiation textbook was elaborated in computer-aided design);
- Information Technology and programming.
Study program provides also teaching the course “Research and Technical Creativity Methodology” for master (Cycle II) students from seven specialties from the Faculty of Mechanical and Technological Engineering, and Transport and “History of the research in the domain”, doctoral students (Cycle III) from 8 faculties. Taking into account the scientific results within the scientific direction “Development of the renewable energy conversion” and laboratories equipped with modern research equipment, the program established a new specialty at the second cycle of studies (Master) – “Systems Engineering of renewable energy conversion “providing teaching of the disciplines:
- Fluids Mechanics;
- Numerical simulation of fluid flow;
- wind energy conversion systems;
- Systems for the conversion of kinetic energy of water;
- Solar energy conversion systems.
Currently all subjects taught within the the Programme are provided with textbooks, guide books for projecting and laboratory. It continues the practice of elaboration of some laboratory works with computer use thanks to licensed software and research equipment obtained due to international grants. Technical and material base and professional training of teachers allow the teaching of postgraduate courses in the fields:
- Computer-aided design of machine parts for design engineers, based on software design, modeling and simulations SolidWorks, ProEngineering, CATIA etc.;
- Basic of creative projecting for and inventics of design engineers based on the creative system in its various aspects: creative product, creative person, creative process, creative environment.
Along the way within the Program of trainings it was established a perfect system of didactic and scientific training by opening various scientific directions. There were published over 1,500 scientific and didactic works, including 30 books and monographs, about 25 projecting and laboratory guide books, made over 300 inventions, some of which were performed in experimental models and industrial prototypes presented at over 70 international exhibitions and appreciated with over 120 gold and silver medals and special prizes.
Study program “Strength of Materials” provides teaching process of the following disciplines within the 3 departments:
- Strength of Materials (were elaborated 2 and translated 3 books and a collection of problems);
- Applied mechanics.
Study program provides also teaching the subject “Modeling of mechanical systems” to master (cycle II) students at 2 specialties from the Faculty of Mechanical and Industrial Engineering, and Transport.
In conditions of the widespread use of computers members of the Department build computing relationships starting from the fundamental model of the mechanics of solid deformable body. Thus the program of studies “Strength of Materials”, course “Strength of Materials” is presented as a particular case of the mechanics of solid deformable body. In the the developed concept succeeds the approach in a unified form of the computing problems to strength, rigidity and stability. Applied mechanics is presented as part of rational mechanics. This teaching model fits the concept of fundamentalization of the training process provided by higher education reform.
The Programme collaborators have published 540 scientific didactic works, including textbooks, monographs.
Study program “Study and Technology of materials” ensures the didactic process at specialties from 5 faculties for the following subjects:
- Study of materials (3 manuals were published);
- Technology of materials
at mechanical profile and
- Study and Technology of materials profiles: management engineering, construction, energetic, food technology, industrial design, etc. Collaborators the Department have published 5 monographs and over 400 scientific-methodic works that contribute to increasing the efficiency of training, such as: “The structure, properties and thermal treatments”, “study materials and welding”, “Study and materials processing” etc..
III. SCIENTIFIC RESEARCH ACTIVITY
A particularly important aspect in the activity of Department was the scientific activity from the Department, which was carried out through:
- researches within the doctoral themes;
- researches within the scientific research contracts;
- researches within international grants;
- fundamental research;
- Technical creativity activities.
The program of studies “Theory of machines, machine parts and mechatronics”
Throughout the existence of study programs there were founded the following scientific directions of research: “The construction of agricultural machinery” (scient.coord.: prof. C. GLUSCO); “The dynamics of fine mechanics mechanisms” (scient.coord.: Z. DONTU); “Tribology” (scient.coord., assoc. prof., V.

Study program “Strength of Materials”
Scientific and technological progress is primarily conditioned by the level of knowledge of the behavior of materials based on the history external action. Contradictions that exist in the treatment of experimental data accumulated in the light of phenomenological theories and models promote the actuality of the problem constitutive equations construction on a macroscopic scale on the basis of physical relations on a microscopic scale.
Currently are established only procedures under which a switch is made from properties on a microscopic scale to the macroscopic scale properties. But numerous experimental results demonstrate with certainty that the behavior of polycrystalline conglomerate structure elements differ from their behavior in free stateă. Therefore, the real properties of the crystals in polycrystals are not known. For this reason, the results which are obtained on the basis of transition from the properties of the crystals obtained in the free state to the behavior of the polycrystalline material is not in good agreement with the experience.
Within the Program was adopted the concept of equivalence of the direct problem with the reversed one. It is considered that from the multitude of constitutive equations being permissible from terms of the principles of thermodynamics correspond to reality only those that allow simultaneous direct and inverse solutions. Based on these restrictions, the general system of equations is completed with additional equations. Based on the condition of uniqueness concerning the real material properties reflection in the mathematical model, it became possible to determine the thermomechanical properties of the crystals in a polycrystalline material. Based on the built structural model can be designed composite materials with rational properties for operating conditions. Constitutive equations built on the basis of the structural model permit estimation of durability of building elements depending on the history of external action. Within the Program were presented a thesis for dr. hab. and 6 for doctor.
Study program “Study and Technology of materials”
Initially, the scientific direction of the Department concerned the engineering of semiconductor materials, headed by the the first rector S. RADAUTANU – a disciple of the world-renowned scientific school from Leningrad headed until now by the great scholar J. Alfeorov who recently became Nobel Prize winner. And S. RADAUTANU soon advanced from candidate (doctor) in technical sciences to academician of AS MSSR. Under the leadership of S. RADAUTANU, the first head of the Department, O. DERID, submitted the Doctoral thesis (candidate) of Science, who later took over the scientific leadership of of this direction. In the period of 1965-1975 within the Department, under the leadership of prof. S. RADAUTANU and O. DERID annually activated 3-4 aspirants (doctoral students). Form these, obtained the title of Doctor – A. STANCIU, GR. DANTU, T. DIOMINA. Also in this direction of scientific activity the Polytechnic Institute was sending young post-graduate (doctoral) to institutions of value from Moscow among whom SAUGA V., N. CIBOTARU, Iu. CIOFU, who supported the theses of doctor in time and were assigned to positions of teachers at the Department STM. V. SAUGA became in 1989 the State Prize Laureate of the MSSR in Science and Technology. In the ҆80, Scientific Directory of the Department has been redirected, becoming closer to the scientific specifics of mechanical faculty. In this period at the Department appeared Doctors in Technical Sciences, specialists in engineering of machine building materials: A. CHETRARU, I. VEREBCEANU, V. CUCONESCU, P. POSTOLACHE. Also Chisinau Polytechnic Institute sent to post-graduate (doctoral) at the Polytechnic Institute from Minsk V. CAZAC, Iu. SOLPAN, V. GOIAN. All three became Doctors in Sciences and returned to the DSTM.
Currently within the Program do not activate any scientific direction, the research scientists being involved in other scientific directions of the Department or from the Institute of Applied Physics of the Academy of Sciences of Moldova.

Two of them – for microscopic analysis and heat treatment – serve the section “Study materials” and the others – for materials processing by plastic deformation, welding and cutting – serve the section “Technology of machines construction materials”.
Members of the Department have had fruitful cooperation in terms of didactic-methodical and scientific aspect with universities and organizations in the country and from abroad, mainly from Romania. Already for 12 years the teaching staff of the study program “Theory of machines, machine parts and mechatronics” participate in methodical seminar SNOM (National Seminar of Machine Elements), organized by the Departments of Parts for Machinery from Romania. In 2004 and 2014 our Department organized SNOM at TUM. Also in the program of academic mobility CEEPUS under three projects over the five year, Program members collaborate with over 20 universities from European countries, where there were made more than 30 visits, especially the young teachers and researchers in partner universities in Poland, Slovakia, Croatia, Bulgaria, Romania, also over 30 teachers from abroad visited the laboratories of the Programme.Within the study program “Strength of Materials” at the the Department there were organized a series of scientific-methodological conferences on methods of calculating at the resistance. Scientific researchers permanently participate in scientific events from abroad.
Members of the Department participated widely in various international scientific events (conferences, exhibitions of inventions and technology transfer, etc.). An area where the scientific collaboration has been especially beneficial is that of research. Along the way, in collaboration with researchers from other universities and organizations have been obtained over 15 research projects within various research programs (CRDF MRDA, SCOPES, BSEC HDF, SEE Transnational Cooperation, Fonds francophone des inforoutes etc.). More than 30 research projects have been developed in cooperation with foreign researchers in various research programs (EU: FP6, FP7, Horison 2020, NATO, TEMPUS, Euro-American STCU, INTAS, French: AUF, Blaise Pascal, Jean Monnet , German DFG, cross-border program “Romania-Ukraine-Republic of Moldova” etc.
