Abstract

According to study of shock wave propagation and fragment movement after explosion of blast fragmentation warhead, a more accurate way was provided for calculation of fragments and shock wave propagation distance and the time delayed. A computing system of fragments and shock wave's movement was developed by using Visual C++. It makes calculation be more convenient. Movement of preformed fragments and shock wave after explosion was simulated. The results show that the simulation tally with the new calculation model and the accuracy is improved by 8.3%.

Key words： fragment; shock wave; motion law; LS-DYNA
