| Abstract: | A simulation model for damage evolution in slip bands under VHCF condition is presented. By use of a numerical method it is applied to a real simulated microstructure of AISI304. It considers orientations of slip systems as well as individual anisotropic elastic properties in each grain. The numerical method is the two-dimensional boundary element method which is based on two integral equations and implies fundamental solutions for anisotropic elastic solids.
