Abstract: The dynamic process and internal mechanism of metal materials under shock loading have always been focused on shock physics fields, which are of great importance in both national basic engineering and development of cutting-edge weapons. Recent research progress of mechanical behavior and mechanics of metal materials loaded by shock wave based on our previous study is reviewed in this paper. We focus on the influence of internal and surface interface microstructure of metal materials on the mechanics of damage and failure processes and introduce the opportunities and challenges of material behavior under complex loading conditions. Finally, direction and key point of future work were discussed.
