Abstract :This study investigates the nondimensional buckling behavior of a functionally graded material (FGM) sandwich nanoplate. The analysis consider variations in material gradation parameter, length ratio, thickness ratio, incline angle, nonlocal parameter and size parameter. Higher-order shear deformation theory (HSDT), Nonlocal strain gradient theory (NSGT), Hamilton\\\'s principle, and the Navier solution with simply supported boundary conditions are employed to derive and solve the governing equations of motion. The effects of nonlocal elasticity, strain gradient elasticity, dimension change of the core layer on the thermomechanical buckling behavior of the sandwich nanoplate have been examined in a broad framework. It is observed that the thickness ratio and incline angle in the core layer are effective on the thermomechanical buckling behavior of the sandwich nanoplate whereas length ratio change has a neglectable results. Material gradation parameter changes buckling behavior significantly. The research provides critical conclusions for the design of FG nanoplates in advanced thermal and mechanical applications, emphasizing the adjustability of buckling behavior via material and structural modifications.
