Lagrangian sharp interface schemes for multimaterials

Abstract

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.
