A new higher order shear and normal deformation theory for FGM sandwich shells

Static and free vibration analysis of simply supported FGM sandwich shells is presented in this paper using a new higher order shear and normal deformation theory. The higher order theory developed herein considers the effects of transverse normal stresses. The theory uses higher order variations of in-plane as well as transverse displacements. Hamilton’s principle is used to formulate the equations of motion. Solutions of simply supported...
