ELASTO-PLASTIC ANALYSIS OF ORTHOTROPIC PLATES AND SHELLS.

Abstract

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)
