AbstractIn this study, a finite element model of the explosive welding process of three-layer plates composed of Ti/Al/Mg was established, and the interfacial behaviors of three-layer plates were researched. We investigated the influences that affect the quality of explosive bonding and explored the influence factors of variable physical parameters in the simulation. The finite difference engineering package AUTODYN with the smoothed particle hydrodynamics method has been used to model the

Wave morphology on the Al/Mg interface and straight morphology on the Ti/Al interface were produced in this study; meanwhile, jet phenomenon occurred obviously in the simulation process. The contours of velocity, pressure, shear stress, and effective plastic strain of Ti/Al/Mg were also discussed. The result of
