DYNAMIC BUCKLING OF VISCOPLASTIC SPHERICAL SHELLS

Buckling is a significant cause of structural failure. A theoretical investigation has been undertaken into the dynamic instability of complete spherical shells which are loaded impulsively and made from a viscoplastic material. The critical mode numbers obtained in this thesis are similar to those obtained for cylindrical shells having the same R/h ratios and material parameters while the threshold velocities were for higher viscoplastic spherical shells than for rigid-plastic spherical shells.
