This Laboratory contains two units (divisions): Division for dynamic testing and Division for engineering software.
Division for dynamic testing is under development.
The Hopkinson bar is the main experimental plant at the Laboratory and it is used for testing of metal and composite test-tubes under very high (impulse) deformation speeds. Our original construction is based on the results of five projects with Joint Research centre, Ispra, Italy (European Commission for Atomic Energy). Without such database, all software for dynamic analysis of constructions is practically useless, because the error of wrong material constants is huge. In order to complete the base with low and medium deformation speeds, different temperatures and damages, we have the results of the projects for crosscut and "bichierino" ("knee cup") test-tubes. This is the only such construction on the area of the former SFRJ.
Main research fields are: visco-plasticity of metals and composites, stability of non-linear vehicle vibrations, multi-axial dynamic experiments, geometrical theory of dislocations, waves in elastic composites and plastic waves, plasticity of damaged and neutron radiant steels, visco-plasticity of ferromagnetics, low-cycle fatigue of austenite steel, non-elasticity of micromorphous polycristals.
The Laboratory has original constructions done by students within their final exams. One of them is based on step motor and simulates programmed motion given by arbitrary time function.
Division for engineering software
Main activities of the Division for engineering software are connected to development of Program for analysis of constructions (PAK) and it application in research and solving of practical problems. PAK is a program of general application for linear and nonlinear static and dynamic analysis, heat conduction, fluid mechanics with heat transfer, coupled problems, biomechanics, fracture mechanics, damage mechanics and material fatigue. PAK program has a level of globally known programs for structural analysis. It is based on top-level theoretical achievements in the field of finite elements method. The authors of the program had published their original scientific results and methodologies from the fields of elastic-plastic analysis, thermo-plasticity, anisotropic behavior of materials, new and improved finite elements, coupled problems, biomechanics, fracture mechanics and other, in a great number of globally known journals nad books. Program is fully documented and has all necessary manuals. The Laboratory constantly supports the training of new users and software maintenance. PAK program is used in education within a large number of subjects at after graduate and final years of studies. Also, the program is used in development of many doctoral dissertations, master's theses and final works at our Faculty and at other faculties in the country.
At the Laboratory for engineering software, there is a constant realization of several projects of the Ministry of science of the Republic of Serbia, and of projects realized in direct cooperation with the economy, in the country and abroad. The most significant users of our program and services are: Institute for water power engineering "Jaroslav Cerni" from Belgrade, Institute for automobiles "Zastava" from Kragujevac, Electrical industry of Serbia, "MV Engineering" - Krefeld - Germany, Freight car factory from Kraljevo, Military technical institute from Belgrade and many others.
