Vibration of nonuniform shear deformable axisymmetric orthotropic circular plates solved by DQEM

A new numerical approach for solving the vibration of nonuniform shear deformable axisymmetric orthotropic circular plate problems is proposed. The approach uses the differential quadrature (DQ) to discretize the governing equations defined on each element, the transition conditions defined on the inter-element boundary of two adjacent elements and the boundary conditions of the plate. It is a differential quadrature element method (DQEM) analysis model. Numerical results of sample problems solved by this DQEM analysis model are presented. They prove that the developed DQEM analysis model of shear deformable axisymmetric orthotropic circular plates is efficient
