Abstract

This study aims at characterizing the influence of gradients at different scales (loading, geometry, microstructure⋯) on fatigue strength through a multi-scale finite element modeling associated to several high cycle fatigue criteria. This is a necessary step in the perspective of conducting a relevant experimental campaign on notched specimen exhibiting a gradient of mechanical properties.
