Abstract
Solution procedures are developed and evaluated for static and dynamic elasto-plastic analysis of structures with material and geometric nonlinear behavior. The mixed finite element approach is adopted. The analytical formulation is based on a form of the nonlinear shallow shell theory that incorporates the effect of shear deformation and bending-extensional coupling. The generalized equilibrium equations are obtained by using a modified form of Hellinger-Reissner mixed variational principle. The elasto-plastic solution algorithm for the static case is based on the tangent stiffness approach. The elasto-plastic algorithm for the dynamic problem is based on the initial stiffness approach. A number of plate and shallow shell structures are solved and results compared to known solutions. The comparison indicates good to excellent agreement with other solution schemes.
