A simple Cartesian scheme for compressible multimaterials
Article dans une revue avec comité de lecture
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 laws, describing for example fluids or hyperelastic solids. The model is fully Eulerian and the scheme is the same for all materials. We show stiff numerical illustrations in case of gas–gas, gas–water, gas–elastic solid interactions in the large deformation regime.

Communication avec acteGORSSE, Yannick; IOLLO, Angelo; MILCENT, Thomas; TELIB, Haysam (2012)We present a method to capture the evolution of a contact discontinuity separating two different material. A locally non-conservative scheme allows an accurate and stable simulation while the interface is kept sharp. ...

Communication sans acteDE BRAUER, Alexia; GORSSE, Yannick; IOLLO, Angelo; MILCENT, Thomas (2013)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 ...
