We propose a simple Cartesian method to simulate the interaction of compressible materials separated by a sharp interface. The model describes fluids, hyper-elastic and perfectly plastic solids in a fully Eulerian frame involving a unique scheme for all materials. The scheme can handle large deformations as well as elastic rebounds.
