Simulations of stress–strain heterogeneities in copper thin films: Texture and substrate effects

Finite element simulations of the elastic and elastic–plastic deformation of copper thin films are performed in the presence or not of substrate. The investigated textures are {1 1 1} and {0 0 1}. In the anisotropic elastic case, {0 0 1} films are associated with more strain heterogeneities than {1 1 1} films. Strong plastic strain heterogeneities are found in {0 0 1} films. The presence of a substrate increases significantly the heterogeneity of stress–strain fields.
