Tóm tắt báo cáo

In this paper, a finite element formulation for bucking analysis of a two-directional functionally graded sandwich (2D-FGSW) beam is developed in the context of a higher-order shear deformable theory. The beam is considered to be formed from a homogeneous isotropic core and two functionally graded skin layers with material properties are graded in both the thickness and length direction by a power-law distribution. The accuracy of the formulation is verified through comparison of the present results with the published data. The buckling loads for the beam with different boundary conditions are computed to illustrate the effects of the material distribution and ratio of layer thickness on the buckling behavior of the beam.
