| Abstract: | The elasto-plastic and geometrical nonlinear anisotropic plates and shells are analysed using three dimensional degenerate shell element and layered model. The shear and membrance locking phenomenon can be effectively overcome using 9-node Heterosis element and selected integration. Examples presented show the applicability and versatility of the given program. |
