Tóm tắt báo cáo

In this paper, the quasi-3D shear deformation theory is adopted to study static bending of a functionally graded sandwich (FGSW) plate. The plate is composed of a homogeneous core and two power-law functionally graded skin layers. A Q4 element with nine degrees of freedom per node is derived and employed in computing the response of the plate under uniform and sinusoidal distributed load. The accuracy of the present finite element formulation is confirmed by comparing the numerical data of present work with the published data. The influence of the power-law index, the layer thickness ration on the deflections and stress distribution of the plate is studied and discussed.
