Abstract
We propose a simple model to reproduce ductile failure by
shear localization in simulations of perforations tests. The model
incorporates a positive feedback process of shear strain localization which
results in a catastrophic decrease of flow stress. We use the model for
perforation tests with 304L stainless steel. It succeeds in reproducing
perforation thresholds as well as qualitative features of the perforation
process, including shear band formation in some of the projectiles.
