“…Numerous investigations of the buckling and post-buckling responses of composite structures in thermal environments can be found in the literature, among which those incorporating temperature-dependent material properties are due to Chen and Chen (1989), Noor and Burton (1992a,b), Argyris and Tenek (1995), Feldman (1996), Deng et al (2000), Lee (2001), Shen (2001) and Singha et al (2003). Significant influence of temperature-dependent properties on the critical buckling temperature and post-buckling temperature-deflection curves has been reported.…”

This paper presents thermo-mechanical post-buckling analysis of cylindrical panels that are made of functionally graded materials (FGMs) with temperature-dependent thermo-elastic properties that are graded in the direction of thickness according to a simple power law distribution in terms of the volume fractions of the constituents. The panel is initially stressed by an axial load, and is then subjected to a uniform temperature change. The theoretical formulations are based on the classical shell theory with von-Karman-Donnell-type nonlinearity. The effect of initial geometric imperfection is also included. A differential quadrature (DQ) based semi-analytical method combined with an iteration process is employed to predict the critical buckling load (where it is applicable) and to trace the post-buckling equilibrium path of FGM cylindrical panels under thermo-mechanical loading. Numerical results are presented for panels with silicon nitride and nickel as the ceramic and metal constituents. The effects of temperature-dependent properties, volume fraction index, axial load, initial imperfection, panel geometry and boundary conditions on the thermo-mechanical post-buckling behavior are evaluated in detail through parametric studies.
