Abstract:

A theoretical investigation is undertaken into the dynamic instability of complete spherical shells which are loaded impulsively. The linear elastic, elastic-plastic and rigid-plastic material idealizations are used in the various theoretical procedures. The threshold velocities for the elastic and rigid-plastic models are larger than those for cylindrical shells having the same Rh ratios and material parameters, while the critical mode numbers are similar.
