“…Thus, the exact analysis of thermal stresses is really important (Ying and Wang, 2010). There have been many studies, such as Timoshenko and Woinowsky-Krieger (1959), Boley and Weiner (1960), Das and Navaratna (1962), Das and Rath (1972), Stavsky (1963) and Thangaratnam et al (1988), which focused on thermal stresses in isotropic homogeneous rectangular plates. Yee and Moon (2002) have been obtained a closed-form analytical solution for the plane thermal stress analysis of a homogeneously orthotropic hollow cylinder subjected to an arbitrary, transient, asymmetric temperature distribution.…”

A novel approach is employed to a general solution for one-dimensional steady-state thermal and mechanical stresses in a hollow thick cylinder made of a functionally graded material (FGM). The temperature distribution is assumed to be a function of radius, with general thermal and mechanical boundary conditions on the inside and outside surfaces of the cylinder. The material properties, except Poisson's ratio, are assumed to be exponentially-varying through the thickness. Forcing functions applied to the inner boundary are internal pressures which may be in form of steps. These conditions result in governing differential equations with variable coefficients. Analytical solutions to such equations cannot be obtained except for certain simple grading functions and pressures. Numerical approaches must be adopted to solve the problem in hand. The novelty of the present study lies in the fact that the Complementary Functions Method (CFM) is employed in the analysis. The Complementary Functions method (CFM) will be infused into the analysis to convert the problem into an initial-value problem which can be solved accurately. Benchmark solutions available in the literature are used to validate the results and to observe the convergence of the numerical solutions. The solution procedure is well-structured, simple and efficient and it can be readily applied to cylinders. It is also well suited for problems in which mechanical properties are graded.

The results, in terms of deflections and stress resultants at various points of the plate, are computed using the present formulation and compared with those obtained by Thangaratnam et al [1]. The results, along with the comparison, are presented in Figures 2-4.…”

The present paper deals with the first ply failure analysis of laminated composite plates under linearly varying temperature through the thickness of the laminate. The plate element has been modeled as an eight noded isoparametric quadratic plate bending element based on Reissner-Mindlin's assumption for the transverse shear deformation. The deflection and stress resultants obtained in the present study are compared with those available in published literature. The stress level causing the failure of the weakest layer has been detected, based on various stress interactive failure criteria viz. Tsai-Wu and Hoffman's criteria. The temperature of the outermost layer has been computed at the stress level of that weakest ply failure. A parametric study has been carried out on the basis of different lamination schemes and boundary conditions. KEY WORDS: thermal stress, first ply failure, finite element method, laminated composite plate.

“…Stiffness and strength are reduced with the increase in moisture concentration and temperature. The deformation and stress analyses of laminated and sandwich composite plates subjected to moisture and temperature have been the subject of research interest in recent years, but most of the researchers have studied the effect of temperature [4][5][6][7][8][9][10]. Wu and Tauchert [4,5] presented closed-form solutions for deflections and moments for symmetric and anti-symmetric laminates subjected to uniform change in temperature in addition to the external loading.…”

“…Effects of aspect ratio, side-to-thickness ratio and laminate construction are considered. Thangaratnam et al [7] used the semiloof shell element for the thermal stress analysis of composite plates and shells. Results for deflections and moments are presented for the linearly varying temperature through the thickness and uniform temperature distribution over the surface.…”

Present research work is based on the unique properties of isogeometric analysis (IGA) like smarter, faster and cheaper analysis for the thermo-elastic bending of laminated and sandwich composite plates. IGA, based on isoparametric concept, is a breakthrough in the area of structural analysis, which employs non-uniform rational B-spline (NURBS) as a basis function to represent less erroneous geometry. Unlike finite-element method (FEM), increasing the polynomial order in IGA gives higher continuous basis functions naturally and easily with reduced computational cost. A procedure has been developed for thermo-elastic bending analysis of laminated composite plates and sandwich structures using IGA approach. The developed NURBS-based code is validated and computational efficacy of thermo-elastic analysis is investigated. A detailed parametric study has been carried out for the quadratic, cubic and quartic NURBS elements with respect to the variation of temperature. Different types of temperature profiles have been considered. Change of deflections, stresses and moment resultants are analysed with an aim to understand the thermo-elastic behaviour of laminated and sandwich composite plates. Several thermo-elastic numerical examples have been analysed extensively. Obtained numerical results are compared with available literature to show the advantage of current formulation.
