Lagrangian sharp interface schemes for multimaterials
TypeCommunications avec actes
We present multi-material simulations in the Lagrangian framework. The methods employed are based on classical Godunov-like methods that are adapted to treat the case of interfaces separating different materials. In the models considered the gas, liquids or elastic materials are described by specific constitutive laws, but the governing equations are the same. Examples of gas-gas and elastic-elastic material interactions are presented.

GORSSE, 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. ...
GORSSE, Yannick; IOLLO, Angelo; MILCENT, Thomas (Springer Berlin Heidelberg, 2014)We present multimaterial simulations using both Eulerian and Lagrangian schemes. The methods employed are based on classical Godunov-like methods that are adapted to treat the case of interfaces separating different ...
BRAUER (DE), Alexia; IOLLO, Angelo; MILCENT, Thomas (2014)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 ...
DE BRAUER, Alexia; IOLLO, Angelo; MILCENT, Thomas (Istituto Nazionale di Alta Matematica, 2015)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 ...
GORSSE, Yannick; IOLLO, Angelo; MILCENT, Thomas; TELIB, Haysam (Elsevier, 2014)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 ...
