On Elastoplastic Cyclic Response of Shell-Like Structures

An efficient numerical simulation technique for elastoplastic cyclic analysis of shell-like structures has been proposed employing realistic highly nonlinear hardening responses. The closest point projection integration algorithm, completely formulated in tensor notation is presented using a Reissner-Mindlin type kinematic shell model. The proposed algorithm has been embedded into a layered assumed strain isoparametric finite element. Numerical example, considering the nonsymmetric loading controlled test, illustrates the stabilization of the load-displacement response.
