Tóm tắt báo cáo

Triple-layered composite plates are created by joining three composite layers using shear connectors. These layers, which are assumed to be always in contact and able to move relatively to each other during deformation, could be the same or different in geometric dimensions and material. They are applied in various engineering fields such as ship-building, aircraft wing manufacture and so on. This paper used Mindlin‘s theory and finite element method (FEM) to describe the oscillation of triple-layered composite plates with shear connectors under the dynamic load. The Matlab programming is introduced to test the reliability of the proposed equations as well as the influence of some parameters such as boundary conditions, rigidity of joints, thickness-to-length ratio and dynamic response of the composite plate.
