摘要：
As a consequence of the elastic and plastic anisotropy of the grains in polycrystalline materials, inhomogeneous stress and strain fields develop in the grain structure. In addition, in two-phase materials, different mechanical properties of the phases lead to further localisation of the plastic deformation. Both effects which influence the development and formation of shear bands as well as the damage process during loading are investigated on polycrystalline Ag and two-phase Ag/Ni by means of the finite element method (FEM).
