N2 - This paper addresses the problem of predicting fatigue damage accumulation in metallic materials accounting for local crystal orientation effects using a multiscale model. Single crystal plasticity is introduced to describe crystalline material behavior. At the mesoscale level, different material properties and crystal orientations are assigned to individual grains in a finite element model. Finally, an average method is used to compute the material properties at the mesoscale, which are then applied to a macroscale representative test structure. To predict fatigue damage evolution, a comprehensive fatigue damage criterion is modified to account for single crystal plasticity.
