Using the Janus LLNL and Omega facilities, we are using laser energy to generate shock and quasi-isentropic compression of monocrystalline, polycrystalline, and nanocrystalline FCC and BCC metallic specimens(Cu, Ni, V). We have investigated the internal defects generated by experimental and computational (MD) means. By comparing experimentally observed and computationally predicted structures we can obtain new insights into the fundamental deformation mechanisms. We have also investigated the mechanisms of spall initiation, propagation, and fragmentation.
