The aim of the course is to provide students with contemporary advanced knowledge in the field of terminal ballistics. The focus of the study are two key areas of terminal ballistics: penetration mechanics and blast effect. The main goal is to successfully use the methods of analytical modeling and numerical simulation of these phenomena.

Having successfully completed the course students should be able to: - apply modern analytical methods for modeling of penetration/perforation processes, - use the advanced numerical predictive techniques for modeling of different classes of penetration processes, - calculate all relevant parameters of blast effect of a warhead, - use numerical methods for modeling of blast effect.

1. Penetration mechanics Recapitulation of impact mechanics and shock wave physics. Characterization of the behavior of materials at high strain rates. Experimental methods of terminal ballistics. Analytical modeling of the dynamics of perforation of metal plates. Analytical models for soil, concrete and ceramics penetration. Eroding penetrators - penetration of long-rod projectiles and shaped charge jet. Numerical modeling of penetration. 2. Blast The formation of the shock wave as a result of the explosion (blast). Modeling of a blast wave. Propagation and reflection of blast waves. Measurement techniques. Scaling blast parameters. Interaction of blast wave and the structure. Numerical simulation of the blast effect.
