Elasto-Plastic Analysis of an Arbitrary Anisotropic Laminated Shell by the Finite Element Method.

Abstract

A procedure for the elasto-plastic analysis of a general anisotropic laminated shell using the finite element method is presented. A curved triangular element with linear membrane displacement and quintic normal displacement is used. The analysis approach taken is that of incremental loads with additional loads being applied to account for the effect of plasticity. The analysis is carried out in conjunction with the Huber-Mises yield criterion and the Prandtl-Reuss flow rule in accordance with the theory of a strain-hardening yield function. To account for anisotropy the yield criterion is generalized by introducing the anisotropic parameters of plasticity. These parameters, although constant within a load increment, are allowed to vary from one load increment to another as the material strain hardens. (Author)
