A finite element displacement method is developed for the elasto-plastic analysis of bi-linear strain-hardening orthotropic plates and shells. Two basic approaches in the elasto-plastic analysis, the initial stiffness approach and the tangent stiffness approach are presented and compared. Three separate computer programs have been written the first two are for the plane stress case. The third program is for the rectangular shallow shells, and it uses elements whose thicknesses are subdivided into equally-spaced layers, each of which is assumed to be in plane stress. Author
