We have carried out a series of multi-million atoms non-equilibrium molecular dynamics and ab-initio molecular dynamics simulations to investigate the effect of crystal orientation over the shock induced plasticity and phase transformation in single crystal copper. Crystallographic orientation of ,  and  has been studied for various intensity of shock ranging from 1.0 km/s to 3.0 km/s. During shock wave propagation along <100> and <110>, a FCC-to-BCT phase transformation has been observed to occur behind the shock front at higher intensity of shock, e.g. above 1.5 km/s of piston velocity for Cu(100). To explore the atomistic mechanisms involved in this structural phase transformation and associated characterization, radial distribution function, adaptive common neighbor analysis and x-ray diffraction pattern has been utilized.
