This paper describes an outline of computer simulation techniques for material failuers under a High Velocity Impact Phenomena.
Basic equations are solved by finite difference method and material models are taken into onsideration of strain rate effect, thermal softning effect, Tillotson's state equation for thermodynanic effect and espcially Mescall's failure criteria.
We are justified for this techniques that are very effective, becase we compared calculation results with experimental ones and confirmed that both are good fitable.
