✦ Synopsis

Thermal buckling analysis of laminated composites is presented by using a layer-wise theory. Governing buckling equations are derived from the variational principle and a finite element method is developed to formulate the problem. Numerical results are obtained and compared with those of other theories addressing the effects of the thickness-to-span ratio, lamination angle, the ratio of thermal expansion coefficients and degree of orthotropy on buckling temperature for antisymmetric angle-ply laminates. It is found that a layer-wise approach may be necessary for more accurate thermal buckling analysis of laminated composites.
