The partial hybrid stress method is applied to higher-order plate theory for orthotropic laminated plates. This new element performs better than displacement formulation and approaches the accuracy of hybrid formulation with much less stress parameters. The governing equations of plate are also derived from the modified Hellinger-Reissner principle.
