Abstract
In this study, an attempt is made to develop an equivalent axisymmetric fragment simulating projectile (FSP) to represent a nonaxisymmetric standard FSP for the development of calibration curves for witness packs, using numerical simulations. Three different axisymmetric FSP models were investigated. In the first model, the cutting edge perimeter of the true FSP was conserved. For the second model, the presented area of the true FSP on impact was conserved. For the third model, the bevel angle was conserved. The results obtained indicate that the third model yields the same ballistic limit as the standary nonaxisymmetric FSP. However, it was found that the plug formation modes for the axisymmetric and nonaxisymmetric models differ substantially.
