Numerical simulation performed by computers is crucial for technology innovation in explosion mechanics.For independent innovations concerning vehicles, equipment and related high-tech areas, such factors as the production technology of key industrial equipment and numerical methods and software technology are essential.Explosion mechanics is the theoretical basis for the design of highly efficient arms and ammunition, involving complex physical and mechanical behaviors of multi-materials at high speed, high temperature and high pressure under extreme conditions.Explosion experimental technique studies occur over a very short period of time and have a strongly destructive effect, yielding a limited amount of experimental data.
