Abstract
Computational modeling of planar impact and Taylor impact at different impact velocities have been examined in this paper
with a new failure criterion proposed by Campagne et al. [1]. The main result of this work is to show the efficiency of our
modeling for the simulation of dynamic plasticity and failure which couples the propose nucleation and growth model with the
Mechanical Threshold Stress model. These models have been implemented in a finite element code ABAQUS/ExplicitV6.2. This implementation
is capable of computing the responses of different targets in various geometries at different velocities. Results of these
simulations are shown and compared with experimental results.
