An Assumed Strain Mixed Formulation for Nonlinear Shellsgenerate solid shell element concept and the Hellinger-Reissner principle with independent strain field. The independent strain field is divided into a lower order part and a higher order part. Using the equivalence between displacement formulation and mixed formulation, the lower order part is repl

Refined Finite Element Laminated Models for the Static and Dynamic Elasto-Plastic Analysis of Anisotnted. 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 analysi
