Tóm tắt báo cáo

This paper studies dynamic behavior of a bidirectional functionally graded sandwich (BFGSW) beam under a moving by using a high-order deformation beam theory. The beam is composed of unidirectional functionally graded core, an isotropic bottom layer and a bidirectional functionally graded top layer. Equations of motion in the context of finite element analysis are derived from energy expressions, and solved by the direct integration Newmark method. The accuracy of the derived formulation is confirmed by comparing the obtained results with the published data. The effects of material and loading parameters on the dynamic behavior of the beam are examined and discussed.
