The micromechanisms related to ductile failure during dynamic loading of single crystal Cu are investigated using large-scale molecular dynamics (MD) simulations. Void nucleation, growth, and coalescence is studied for a singlecrystal Cu system under conditions of impact of a shock piston with a velocity of 500 m/s. The compressive shock wave generated reflects from the rear surface as a tensile wave and meets with the tail of the shock wave at the spall plane. The interaction results in adoi:10.1016/j.proeng.2011.04.598 fatcat:ctpsk3c22rhwhhqfxfzqgap7su
