Abstract A calculation is carried out for a spherical explosive charge in elastic-plastic materials with different yield points. Velocity and stress profiles are shown for several instants of time. The zone of increase of internal energy of the material, due to plastic flow, is shown. The values of the energy in the cavity and also the kinetic and plastic energies of the medium are calculated. Comparison with an experiment carried out with an explosion in aluminum [1] showed satisfactory agreement between the calculated and experimental velocity profile at the free surface.
Type of Medium:
