Abstract: With the continuous increase in demand in both military and civilian sectors, equipment protection will face challenges such as explosive impacts, e.g., the impact of airborne explosion waves on aircraft, missiles, and police blast-resistant suits. Under the influence of explosive loads, the interactions between different parts of the structure, as well as the effects of material and geometric nonlinearity, make the dynamic mechanical behavior exceptionally complex. Therefore, the dynamic response and protective performance of structures under explosive loads have become a hot and challenging issue that urgently needs attention. This article provides a detailed review and summary of the current research status in the field of explosive impact. First and foremost, it reviews the empirical formula calculations, numerical simulations, and experimental research on the propagation characteristics of explosive loads. Furthermore, it elaborates on the dynamic response of typical protective design materials such as porous materials, ceramics, fiber-reinforced composites,and homogeneous metals under the effect of explosive loads, as well as the progress in the design research of impact-resistant structures. The research content involves structural damage and destruction effects, blast energy absorption characteristics, and protective design. Finally, the article concludes and provides prospects for this research field, highlighting several key research challenges that need to be analyzed and addressed urgently. It aims to provide references and guidance for the subsequent design of blast-resistant structures.
