Abstract：As an efficient solid-state composite technology of materials,explosive welding has unique advantages in the preparation of dissimilar metal structures.Its process involves multi-physics coupling problems such as explosive shock wave propagation,high-speed material collision and interface metallurgical bonding.In recent years,with the progress of computational mechanics and numerical algorithms,the numerical simulation research of explosive welding has made remarkable progress in revealing the formation mechanism of interface waves and optimizing dynamic parameters.This paper systematically reviews the key methods and applications of numerical simulation of explosive welding,including the development of typical numerical models at macro and meso scales and the application of molecular dynamics at micro scale,and provides a reference for subsequent improvement of numerical simulation prediction ability and guiding value of complex explosive welding processes.
