Thermomechanical postbuckled vibration response of doubly curved sandwich shallow shells with FGM core layer and hybrid face layers

Abstract This study models and analyzes the thermomechanical vibration behavior of doubly curved sandwich shallow shells using a novel high-order sinusoidal shear stress theorem. The equations of motion are derived from Hamilton's principle and solved with the Navier method. The doubly curved sandwich shell comprises a functionally graded core layer and a hybrid surface layer made of metal and ceramic. The analysis extensively examines the effects of the FGM core layer, hybrid surface layers, ra
