摘要

Thermal postbuckling characteristics of 3D braided rectangular plates are investigated. A 3D braided composite may be treated as a cell system and the geometry of each cell is deeply dependent on its position in the cross-section of the plate. Based on Reddy's higher-order shear deformation plate theory, a perturbation technique is employed to determine buckling temperatures and postbuckling equilibrium paths of simply supported 3D braided rectangular plates. The results reveal that the temperature-dependent properties, geometric parameter, fiber volume fraction and braiding angle have a significant effect on thermal postbuckling behavior of braided composite plates.
