Abstract:

In this paper, the high cycle fatigue problems are studied by means of the method of damage mechanics. The coupling effect between stresses and damage is considered. The fatigue lives of plate specimens with notches are predicted by the finite element method.The comparisons between the computational and experimented fatigue curves show that the errors of the predicted lives given by this method are permissible in engineering applications.
