Simulation and Welding Window of Three Layers Explosively Bonded AA5083 and AA1050 Aluminum Alloys to Carbon Steel

In this research, the effect of standoff distance and explosive material thickness on the Interface properties of three layers explosively bonded AA5083 and AA 1050 aluminum alloys to carbon steel by ABAQUS version 6.9 finite element software was investigated. For the simulation, Johnson cook equation and Williams Burg equation was used for the simulation of plates and explosive materials behaviors respectively. The simulation results showed that in the constant explosive ratio by increasing the standoff or in the constant standoff by increasing the explosive ratio, flyer and interlayer plates velocities and also dynamic collision angle increased. All the experiments placed in the welding windows properly. Interface strength decreased by formation of brittle intermetallic compounds and locally melted zones at the front of vortices.
