Abstract

Abstract

Based on the impact dynamics and the basic theory of explosive welding, the material point method was applied to study the wave formation at the compounded interface by explosive welding, and the corresponding three－dimensional numerical simulations were presented.The interfacial wave formation and plasticity flowing deformation were explored, and the simulated results by the material point method were compared with the explosive welding experiments.The above investigations display that the formation of the interfacial wave in explosive welding result from melting of the metal material and flowing of the eddy at the impact point.Furthermore, the material point method presents an outstanding advantage in the numerical simulation for the interfacial wave formation in explosive welding.
