Thermal Buckling of Coated Functionally Graded Plates Under Nonuniform Temperature Rises
Authors: , , , ,
Abstract: Recently, the functionally graded (FG) concept used in different mechanical engineering applications has become an important solution for delamination problems due to the brutal transition of material composition. The specific goal of this study is the determination of theoretical solution of the critical buckling temperature for rectangular FG plates with a ceramic coating, subjected to the sinusoidal and power law temperature rises. By applying the Galerkin method, the critical buckling load model is obtained. Based on obtained results, the effect of coated functionally graded parameters, namely the coating thickness, the power law index, the initial imperfections and the temperature rise type on the thermal buckling is discussed. This study is useful for the design engineers to choose the coating thickness, the geometrical parameters and the optimum composition as desired to assure the stability of structures subjected to a non-uniform temperature distribution.
