Abstract: In this paper, a lagrangian arbitrary triangular mesh finite volume method for numerical simulating 2-dimensional high velocity impact problem is described. The elasticity and plasticity of material are considered. Some computational results of several impact examples are shown.

Key words: high velocity impact, lagrangian method, finite volume method
