A significant influence of explosive charge geometry is frequently observed during experimental testing.In this paper, the effect of explosive charge shape, along with its material properties, on the generatedblast waves is studied. The FEM analysis was conducted for six different explosive materials and threedifferent cylindrical shapes, with geometrical proportions of length L to diameter D varying between 2, 1and 0.25 and constant charge mass. We found that the blast wave generated by detonation is susceptibleto shape changes. However, the different explosive materials were influenced by the charge shape in almostthe same way, with only insignificant differences resulting from the material properties.
