A new analytical approach of nonlinear thermal buckling of FG-GPLRC circular plates and shallow spherical caps using the FSDT and Galerkin method

A new analytical approach for nonlinear thermal buckling of Functionally Graded Graphene Platelet Reinforced Composite (FG-GPLRC) circular plates and shallow spherical caps using the first-order shear deformation theory (FSDT) is presented in this paper. The are assumed to be subjected uniformly distributed loads. By applying Galerkin method, relations between load–deflection achieved determine postbuckling behavior critical loads considered structures. Special effects on with five different material distribution laws, platelet (GPL) mass fractions, geometrical dimensions explored discussed numerical examples.
