Abstract

An extreme form of strain localization, known as shear-banding, is an important phenomenon in many engineering applications and processes especially in high strain-rate settings such as those encountered in ballistic impact. Concrete knowledge and robust computational tools for simulation of shear localization will help to predict these failure modes and optimize designs. It is well known that classical finite-element simulations of shear-banding can produce extremely mesh dependent results. Peridynamics, a non-local theory, is applied in this research to resolve this problem. Peridynamic simulations are compared to finite-element simulation results and show a regularization effect on the strain-localization.
