Simulations of stress-strain heterogeneities in copper thin films: Texture and substrate effects
Abstract
Finite element simulations of the elastic and elasticplastic deformation of copper thin films are performed in the presence or not of substrate. The investigated textures are {111} and {001}. In the anisotropic elastic case, {001} films are associated with more strain heterogeneities than {111} films. Strong plastic strain heterogeneities are found in {001} films. The presence of a substrate increases significantly the heterogeneity of stressstrain fields.
