Three dimensional numerical simulation for explosive welding

Explosive welding process was numerically simulated with 3D by nonlinear finite element softwareMSC.Dytran.Velocity and pressure distribution were also calculated during explosive welding process.The numerically simulated results were compared with theoreticaly calculated results, which showed that the numerically simulated results were much similar with theoretic results.The results indicates that the mathematical model can be exactly to simulate explosive welding.Velocity and pressure distribution during explosive welding process can be simulated simply by Dytran.However, it can' t simulate the formation of jet and wave-form in explosive welding.The simulation can be referred to explosive welding technology.
