Abstract
A refined finite element shell model for the numerical analysis of thick or thin anisotropic laminated shells under static or dynamic loading is presented. A layered approach is adopted for solution with displacement variables assumed at each laminate interface. Elastic-plastic numerical analysis is performed based on flow theory and a Huber-Mises yielding surface extended by Hill for fully three dimensional anisotropic materials. Dynamic analysis is based on Newmark’s algorithm used in conjunction with the Hughes and Liu predictor corrector scheme. Numerical results obtained for laminated shells are presented and the effects of boundary constraints on the load/boundary deformation characteristics and on the spread of plastic zones are discussed. Comparisons are made to show the effects of anisotropy and bending/stretching coupling on the elastic-plastic response. The effects of lamina angle sequence on the structural characteristics are also illustrated.
