Simulace krutové zkoušky metodou konečných prvků

Abstract

In the present work, torsion plastometric tests of Cr-Mo-V steel are evaluated to the mathematical model, describing the dependence of flow stress on the equivalent strain. Obtained constants can be use in computer simulation. By finite element software FORGE 2008 was computed simulations of torsion tests. In the thesis are showed the results of 15 simulations with different input parameters. The most acceptable results were compared with course of torque on time, experimentally measured by torsion plastometer SETARAM.
