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.
