Analytical, Experimental, And Numerical Study Of Vertical Velocity And Vertical Displacement Profiles, Required Pressure And Final Product Dimensions During Cone Explosive Forming

Explosive forming of cone was investigated from some new analytical, numerical, and experimental aspects. In the analytical modeling, it is supposed that deformation profile of plate is a truncated cone during process, which will be deformed to a fully formed cone at the end of process. The variation of plate thickness was also neglected. Analysis required equations for determining vertical velocity and vertical displacement profiles during process; required pressure and final product dimensions are also given in this analytical model. ABAQUS/Explicit package was used for FEM simulation. The results of analytical model given in this paper are fully agreed with experimental and numerical (FEM) results.
