Abstract
The paper discusses the effect of stress state and of loading with respect to the rolling direction on damage and failure of anisotropic ductile sheet metals. For the investigated aluminum alloy EN AW-2017A experiments with uniaxially and biaxially loaded flat specimens have been performed to identify elastic–plastic material parameters. The focus is on numerical analysis on the micro-scale examining the deformation and damage behavior of differently loaded void-containing unit cells to detect damage and failure processes. Results of the finite element calculations show that the stress state and the loading direction with respect to the rolling direction have an effect on formation of damage mechanisms on the micro-level as well as on corresponding macroscopic damage strains.
