.... A nonclassical model is developed for circular Mindlin plates subjected to axisymmetrically distributed loading by using a modified couple stress theory and Hamilton's principle. The governing equations and boundary conditions are simultaneously derived by employing a variational formulation. The new model...

... formulation is production of a symmetric stiffness matrix similar to that obtained in the finite element method. Numerical examples are presented to demonstrate the accuracy and the validity of the proposed formulation. boundary element method variational formulation shear-deformable plates stiffness...
