OBJECTIVES

The seminar presented the calculation methods of fatigue life of the component to optimize the life through the analysis of the project parameters. The seminar gives the participants a detail on the different theoretical and industrial approaches for the calculation of fatigue life of structural components.

PREREQUISITE

Basic knowledge about the finite element method
