Pocketknives are inexpensive and easily obtained while in Thailand firearms have also become readily available. Some people are lucky and survive gunshot wounds; articles carried in their shirt pockets, especially a metal pen, may increase survival chances. Deformation behavior of a cylindrical object and a stainless steel pen impacted by a 9 mm FMJ (full metal jacket) bullet were investigated under various conditions. Finite element analysis (FEA) was applied to simulate different shooting conditions. Comparison of FEA shooting test simulation results revealed that a cylindrical object and stainless steel pen behaved in a similar manner. Simulation results can be useful to support forensic science examinations. Analysis of the findings indicated that having a stainless steel pen in your shirt pocket may improve the chances of surviving a bullet wound.
