✦ Synopsis

Thermal buckling behavior of composite laminated plates was studied by making the use of finite element method. The thermal buckling mode shapes of cross-ply and angle-ply laminates with various E 1 /E 2 ratios, aspect ratios, fiber angle, stacking sequence and boundary condition were studied in detail.

The results indicate that the high E 1 /E 2 and a 2 /a 1 ratios of AS4/3501-6 and T 300/5208 laminates produce higher bending rigidity along the fiber direction and higher in-plane compressive force in a direction perpendicular to the fiber direction. Therefore, the higher thermal buckling mode shapes are formed. The thermal buckling mode that composite laminated plate will buckle into is mainly dependent on the E 1 / E 2 ratio, a 2 /a 1 ratio, fiber orientation and aspect ratio of the plate.
