Investigation of shock front in nanocrystalline CuTa alloy via molecular dynamics method

CuTa alloy is a typical alloy with high melting point, corrosion resistance and excellent ductility, which is expected to be used as a warhead material for weaponry. In present study, molecular dynamics (MD) method is used to reveal the thermal and mechanical responses of copper-tantalum alloys under high velocity impact from the atomic scale. The model of the nanocrystalline polycrystalline CuTa ...
