Abstract

In the axisymmetric formulation, the buckling failure and postbuckling behavior of an elastoplastic spherical shell under uniform all-around compression are considered. The solution of the geometrically and physically nonlinear problem is based on the finite element method and the explicit finite-difference time-domain scheme. The computation results are compared with experimental data.
