In order to realize numerical simulation of fast transient events, some wave propagation codes, which allow studying the time resolved development of shock wave propagation due to penetration, and detonation, were developed. In this article, Eulerian Multi-material and Arbitrary Lagrangian Eulerian formulations are used. Both formulations have already been used with success in the simulation of fluid with large motion such as the tank sloshing modeling, the overdriven detonation or the simulation of metal cutting processes. This article describes an air-blast simulation using an explicit finite elements code LS-DYNA. The main aim of this investigation is to compare numerical results with experimental results in order to prove the abilities of Eulerian Multi-Material and ALE formulations to treat air-blast problem using an explicit finite element method.
