Summary
The differential quadrature element method (DQEM) has been developed for solving various engineering and scientific problems [1]. Generalized DQ methods can also be used for the DQEM analysis [2,3,4,5,6].

The analysis of nonuniform shear deformable axisymmetric orthotropic circular plates resting on a two-parameter foundation is frequently necessary in modern engineering design. Certain numerical methods can be used to solve this Pasternak type structural problem. A rather efficient method that can be used is the DQEM.

The development of the differential quadrature element method (DQEM) of solution for nonuniform shear deformable axisymmetric orthotropic circular plates resting on a two-parameter elastic foundation was carried out. The DQEM uses the DQ model to discretize the governing differential equations defined for each element, the transition conditions defined on the inter-element boundary of two adjacent elements and the boundary conditions of the beam. Numerical results solved by the developed numerical algorithms are presented. The convergence of the DQEM analysis models developed is efficient.
