Numerical Simulation of Metal Particle Scattering Driven by Explosive Based on ANSYS/LS-DYNA

In order to avoid the damage of ammunition to irrelevant personnel in modern war, low collateral damage has been more and more important in urban combat. This paper studied the key problems in the design of a controllable warhead with low collateral damage. In the design of a controlled warhead with low collateral damage, numerical simulation of explosive driven metal particle scattering was carried out based on ANSYS/LS-DYNA, and the acceleration process of explosive driven metal particles was obtained, and the curves of different mass metal particles with time were given. In addition, the scattering law of the same mass explosive of driving different mass metal particles was also summarized. The above research can provide theoretical basis for the design of a controllable warhead with low collateral damage.
