Abstract

This bachelor thesis deals with determining the fatigue life expectancy of a part under cyclic uniaxial stress. Life cycle of a material is a parameter needed for correct design of majority of machine components. This thesis contains a brief overview of basic findings about fatigue related processes in materials. The text includes short list of both commercial and freely available fatigue life solvers. Comparison of analytical calculation of fatigue life of a part with a calculation of the exact test by Fatigue Tool module in Ansys Workbench environment and the final evaluation of the gained data from both of the previously mentioned methods of calculation.
