Abstract:

Analytical, numerical and experimental results are compared in a systematic investigation of the effects of projectile shaped on thin plate perforation. The analysis of five low velocity impact involving optimal-, ogival-, Russian-, conical- and cylindrical-head projectile comprise the study. A three-way comparison of simple perforation theory predictions, HELP numerical solutions and available experimental data is made for the five problems. The HELP solutions are in excellent agreement with the experimental data. Although the simple perforation formulas are sensitive to projectile shape, they do not provide adequate residual energy predictions. Further numerical studies of this type should provide additional insight into the penetration process and eventually lead to improved perforation formulas.
