Free vibration analysis of functionally graded material sandwich plates is studied using a refined higher order sandwich panel theory A new type of FGM sandwich plates, namely, both functionally graded face sheets and functionally graded flexible core are considered The functionally graded material properties follow a power-law function The first order shear deformation theory is used for the face sheets and a 3D-elasticity solution of weak core is employed for the core On the basis of continuities of the displacements and transverse stresses at the interfaces of the face sheets and the core, equations of motion are obtained by using Hamilton’s principle The accuracy of the present approach is validated by comparing the analytical results obtained for a degradation model (functionally graded face sheets and homogeneous flexible core) with ones published in the literatures, as well as the numerical results obtained by finite element method and good agreements are reached Then, parametric study is conducted to investigate the effect of distribution of functionally graded material properties, thickness to side ratio on the vibration frequenciesread more
