Abstract: 

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.
