Abstract
Elasto-Plastic analysis of plates has been underlain by those theries mostly for the bending, with membrane effects considered, or the large diflection which are hardly accountable for other prime considerations of the shear effects. This report presents a method to take account of them by extending Reissner's approach, which can reasonably include the effects notably of transverse shears in terms of force and deformation, so that the inelastic range can be covered also in that direction owing to laminated types of finite elements. The subject matter is quantitatively discussed in a series of examples of plates differing in their relative thickness.
