A full compatible three-dimensional elasticity element for buckling analysis of FGM rectangular plates subjected to various combinations of biaxial normal and shear loads
Buckling under various biaxial normal and shear load combinations is investigated. The 3D elasticity theory rather than the approximate plate theories is used. A full compatible 3D Hermitian element with 168 degrees of freedom is used. The stress continuity is guaranteed in the present approach. Results are extracted based on a Galerkin-type orthogonality.
