Abstract

We have analyzed the initiation and propagation of the adiabatic shear band in a double-notch shear specimen subjected to impact loading. The explicit time integration finite element code (Abaqus) was used. The plastic behavior of the material is modeled by a thermoviscoplastic power law and elasticity is assumed isotropic. The numerical simulation takes into account the effects of inertia, strain hardening, strain rate hardening and thermal softening. The velocity of the shear band propagation and the critical shear strain for localization are predicted for strain rates varying from 2.5 103 s-1 to 105 s-1.
