Summary: | A higher order layer-wise laminated theory based on quadratic ‘inplane’ displacement variation and linear transverse displacement variation over the thickness of each layer is presented. A generalization of Reissner's variational theory is employed to set up consistent coupled constitutive equations for force resultants in the lamina. Continuity of tractions as well as displacements across interfaces is enforced. The theory is able to represent the distribution of stress over the thickness much better than the lower order discrete laminate theories currently available. As an illustration, the theory is applied to stress analysis of free-edge delamination specimens. |
