Static analysis of functionally graded sandwich plates using a simple quasi-3D trigonometric shear deformation theory

Abstract

This paper presents a new numerical approach based on the Moving Kriging-interpolation meshfree method integrated with the simple quasi-3D trigonometric shear deformation theory to analyze the static of functionally graded sandwich plates. The theoretical model presented herein retains only four governing equations accounts for both shear deformation and thickness stretching effects, and satisfies the zero traction boundary conditions on the top and bottom surfaces of the plate without using shear correction factor. Numerical examples were performed to confirm the accuracy and efficient of the proposed method in predicting the static responses. The effect of the gradient index on the static behaviour of the functionally graded sandwich plates is also investigated.
