Shape forming of shock wave loaded viscoplastic plates

If metal plates are subjected to impulsive loadings a conical shape of the inelastic deformed plates can occur. In the contrary quasi-statically loaded structures, show a more spherical shape of their inelastic deflections. In the present study, an explanation for the development of conical shapes in the case of shock wave loaded plates is proposed based on wave propagation phenomena. The effect of shape forming is studied experimentally with a shock tube and numerically with finite element simulations.
