Analysis of cone forming explosive of and a comparison of experimental, FEM and analytical results

Explosive forming of cone was investigated from some new analytical, numerical and experimental aspects. In the analytical modelling, 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 cone dimensions, distribution of plate center velocity and displacement, distribution of hoop strain during process and required charge mass to produce fully formed cone are also given in this analytical model. ABAQUS/Explicit package was used to FEM simulation. The results of analytical model given in this paper are in agreement with experimental and numerical (FEM) results.
