An attempt has been made to investigate the effects of crystallographic orientation (e.g. <100>, <110> and <111>) over the dislocation dynamics, originated due to shock compression with various intensities, through large scale non-equilibrium molecular dynamics (NEMD) simulation. Due to the geometrically favorable orientations of the operative slip planes in <100>, simple glide based plasticity, including stacking faults (SF), dislocations and twining has been observed to be predominated. For other directions, <110> and <111>, formation of jogs and multiple slips are observed, along with significant delocalization of shear strain in the deformed microstructure. During the reactions of Shockley partials, Hirth-type locking is significant in case of <100>, whereas, Stair-rod and Frank type sessile locks predominates in other above mentioned directions due to complex geometrical orientations of highly dense planes. Temporal evolution of details statistics of the dislocation density and analysis of associated deformation microstructures will be discussed during the presentation.
