What is it about?
A numerical scheme for buckling analysis of functionally graded circular plate (FGCP) subjected to uniformly radial compression including shear deformation rested on Pasternak elastic foundation is presented. The stability equation based on shear stress–free surface is solved by the spectral Ritz method. The spectral Ritz method has good flexibility in the sense of satisfying the boundary conditions.

Why is it important?
Two schemes for buckling analysis of FGCP based on HSDT and CPT are provided. New displacement field based on traction free surface and neutral plane is offered. The proper adhesive functions for satisfying boundary conditions are proposed. A modified Euler-Lagrange equation based on CPT is obtained and then solved. The better results based on HSDT in comparison to other works are obtained.
