Abstract
Continuum crystal plasticity finite element modeling has been used to address size-effects during indentation of thin-metallic films. Berkovich indentation simulations were performed in the frame of continuum crystal plasticity to study the influence of a rigid fcc single-crystalline silicon substrate on a soft thin-metallic copper fcc single crystal film with different crystallographic orientations. It has been observed that crystallographic orientation of the indented plane has a great influen...
