Dynamic plastic buckling of spherical shells during collapse

OSTI ID:6092286
Conditions are established that lead to the growth of initial displacement imperfections (buckling) of complete spherical shells during significant inward motion. This preliminary study is limited to axisymmetric buckling modes only. Shell thickening during inward motion is taken into account, and its effect is found to be important for the stability and maximum growth of a given initial imperfection mode. Upper and lower bounds on the initial, uniform impulsive velocity loading are found (in terms of spherical shell geometry and material parameters) such that growth of initial displacement imperfections remains less than a prescribed multiplier when initial inward velocity lies outside the bounded region. 10 refs., 8 figs.
