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.

We aim to simulate the interactions at the material interface of two compressible media. These interactions are modeled by a single fully Eulerian system of conservation laws. The materials differ by their constitutive ...

We describe a numerical model to simulate the non-linear elasto-plastic dy- namics of compressible materials. The model is fully Eulerian and it is discretized on a fixed Cartesian mesh. The hyperelastic constitutive law ...

We model the three-dimensional interaction of compressible materials separated by sharp interfaces. We simulate fluid and hyperelastic solid flows in a fully Eulerian framework. The scheme is the same for all materials and ...

This paper is devoted to the 3D extension of a sharp interface multimaterial method. We present preliminary results for 3D stiff cases of shock air/helium/water interaction and impacts of projectiles on elastic bodies ...

We present a simple numerical method to simulate the interaction of two non-miscible compressible materials separated by an interface. The media considered may have significantly different physical properties and constitutive ...
