Fig. 8. (A) Final deformed configuration of square honeycomb panels after impingement of three consecutive shocks. Peak over-pressure of all shocks are equal to P = 80 MPa and critical plastic strain of HY80 was assumed to 0.4. (B) Normalized maximum deflection of the bottom face of the square honeycomb sandwich panel made of HY80 subjected to single or two equi-peak shocks versus the effective peak pressure. The results are plotted for three different critical plastic strains of HY80 steel, 0.2, 0.4 and 0.6. Note that for panels subjected to a single shock, the effective peak pressure is equal to the shock peak over-pressure. In all diagrams, sandwich panel has M = 156 kg/m2, L = 1 m and rho-sub-c = 0.04.
