Abstract

Dislocation Dynamics Dynamic Plasticity High Strain Rate Multiscale
The dynamic deformation in FCC single crystals is investigated using a multiscale dislocation dynamic plasticity model. We examine the effect of strain rate, pulse duration, nonlinear elastic properties and crystal anisotropy on wave profiles and dislocation microstructures. The morphologies of the relaxed configurations of dislocations microstructures show formation deformation bands.
