Abstract


In this work, impact ballistic of Cu-10wt%Sn frangible bullets is studied. The main objective of this study is to numerically investigate fragmentation and frangibility of the frangible bullet upon impacting a hard target. The fracture simulation is carried out using explicit finite element (FE) with element deletion/erosion technique to simulate the bullet-target interaction. The model employed maximum strain fracture criterion to model the bullet fracture. The applicability and capability of explicit FE model for simulating the bullet fracture are examined. Numerical results are validated against the experimental results.

Keywords
