Abstract
A multiphase Eulerian formulation for the interaction of visco-plastic compressible solids and compressible fluids is proposed. The plasticity effects in solids are described by relaxation terms in the governing equations which are compatible with the Von Mises yield criterion. The visco-plastic model is validated on experimental data in a range of the impact velocity : a high velocity symmetric rod-on-rod impact experiments, as well as low velocity impacts of jelly-like materials. A good agreement between numerical and experimental results is found.
