A study of issues of impact dynamics based on the SPH method

Based on the SPH method, this paper investigates a number of key issues in shock dynamics, including the nonlinear phenomenon and its influencing factors in the propagation process of shock waves, and the process and mechanism of the interaction between shock waves and the surface of an object. Through the design of the experiments and the analysis of the results, the main conclusions and contributions of this study are drawn. At the same time, deficiencies and directions for further improvement are also pointed out, and prospects and suggestions for future research on impact dynamics are presented. This study is of great significance in promoting the research of impact dynamics.
