The proposed project is directed to finding out basic parameters which describe a froming process in order to be possible to create a mathematical model for dependece of deformation resistance on two variables, deformation and temperature. It includes carrying out experimental tests of selected steels at temperatures from 20 C to 700 C. The results will be published in the form of tables, equations and graphs in a registr and in computer system. Dependence of hardness on temperature of heating and logarithmic degree of deformation will be considered for select material. The part of the project will be development of measurement and elaboration during a compression test of material, too. The new technics implies a fundamental decreasing of time-consuming of measurement. The published register and the computer system will serve not only to the students as teaching aids but also to technologists or designers in engineering industries.
