Abstract

Dislocation Dynamics Dynamic Plasticity High Strain Rate Multiscale Shock loading
The high strain-rate deformation in copper single crystals is investigated using a multiscale dislocation dynamics plasticity model. In this study, we examine the effects of crystal orientation and anisotropy on wave profiles, dislocation density histories, and dislocation microstructures. The morphologies of the relaxed configurations of dislocation microstructures show formation of deformation bands. The number and thickness of these bands are observed to be dependent on crystal orientations.
