Abstract The dynamical response of materials to multiple shock waves is a critical issue in shock physics and
engineering applications. In this work, hydrodynamic simulations are used to investigate the shock-induced
spall failure and subsequent recompression characteristics of tin, under the implementation of a multiphase equation of state, multi-phase constitutive relations, and a damage model. As within experiments,
double shock loadings in simulations are driven by layered impactors with different shock impedances. In
general, our numerical calculations agree well with recent tin spall experiments and reproduce the free
surface velocity characteristics. Interesting dynamic behaviors such as… More >
