NUMERICAL SIMULATION OF TARGET THICKNESS EFFECT ON THE PENETRATION OF STEEL PLATES

This paper presents a research work on rapid dynamics analysis where the main objective is the application of the finite element method to solve ballistic penetration problems using LS-DYNA. To achieve a reliable methodology in LS-DYNA code, several runs are performed and their results are compared with the experimental data. The main problem addressed here is the penetration of hardened tool-steel rod in steel plates with various thicknesses. In this paper the effects of target plate thickness in the ballistic limit and failure mode is also investigated.
