Eulerian model of immersed elastic surfaces with full membrane elasticity
TypeCommunications avec actes
We introduce an Eulerian model for the coupling of a fluid governed by the Navier- Stokes equations, with an immersed interface endowed with full membrane elasticity (i.e. including shear e ects). We show numerical evidences of its ability to account for large displacements/shear in a relatively simple way, avoiding some drawbacks of Lagrangian representation.

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 ...
DE 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 ...
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 ...
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 ...
