| Abstract: | The present investigation deals with the post buckling analysis of the moderately thick angle-ply laminated composite rectangular plates under in-plane uniform temperature induced loading. von Karman type geometrical nonlinearity and first order shear deformation theory are employed in the formulation of the problem. Nonlinear governing differential equa- tions of equilibrium are linearized by quadratic extrapolation technique and resulting linear differential equations are solved iteratively, using Chebyshev polynomials. The boundary con- ditions consisting of clamped. simply supported and their combinations are considered. An incremental iterative approach is employed to estimate the critical/buckling temperatures. The effects of b/a, a/h, boundary conditions, Iamination scheme, Young's moduli ratio and ratio of coefficients of thermal expansion on post buckling behaviour are investigated. |
