文摘内容 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 equations of equilibrium are linearized by quadratic extrapolation technique and resulting linear differential equations are solved iteratively,using Chebyshev polynomials.The boundary conditions consisting of Clamped,simply supported and their combinations are considered.An incremental iterative approach is employed to estimate the critical/buckling tepmeratures.The effects of b/a,a/h,boundary conditions,lamination scheme,Young's moduli ratio and ratio of coefficients of thermal expansion on post buckling behaviour are investigated。
