Polycrystalline and monocrystalline (〈1 0 0〉 and 〈1 1 0〉) vanadium was subjected to shock compression followed by tensile wave release to study spall and fragmentation behavior. The shock pulse was generated by a direct laser drive at energy

Shock compression of mono- and nanocrystalline (nc) nickel is simulated over a range of pressures (10–80 GPa) and compared with experimental results. Contributions to the strain from the various mechanisms of plastic deformation such as partial dis

It is shown that the short pulse durations (0.1 to 10 ns) in laser shock compression ensure a rapid decay of the pulse and quenching of the shocked sample in times that are orders of magnitude lower than in conventional explosively driven plate impac

Single crystalline copper was subjected to quasi-isentropic compression via gas-gun and laser loading at pressures between 18GPa and 59GPa. The deformation substructure was analyzed via transmission electron microscopy (TEM). Twins and laths were evi

Copper and copper aluminum (2 and 6 wt% Al) with orientations [0 0 1] and [1 3 4] were subjected to high intensity laser shocks (energy levels of 40–300 J; energy densities of 15–70 MJ/m 2 and durations below 10 ns). In situ X-ray diffraction and

Fragmentation is a fundamental material process that naturally spans spatial scales from microscopic to macroscopic. We developed a mathematical framework using an innovative combination of hierarchical material modeling (HMM) and adaptive mesh refin

Shock-wave compression is an extreme regime of deformation characterized by strain rates on the order of 106–1010 s−1, pressures ranging from a few to hundreds of GPa, and shock and residual temperatures that can exceed the melting point. These s
