Modelling of the deformation of highly porous metals and alloys under dynamic loading

Abstract

The study represents the analysis of numerical simulation of the failure of aluminum targets made of highly porous or solid 2024 alloy under dynamic loading. The calculations employed the finite elements method in three-dimensional formulation with the use of proprietary programs. The article presents the results of the numerical simulation of Taylor’s test for the projectile made of highly porous aluminum 2024 alloy at the velocities of 75 to 175 m/s. These results are in a good agreement with the results of the experiments. The peculiarities of the destruction of highly porous aluminum targets are shown.
