Abstract

On the basis of accurately considering axial extension and the first-order transverse shearing, geometrically nonlinear governing equations for composite sandwich beams with elastic support, subjected to thermal loads, are formulated. By using a shooting method, the two-point boundary value problem for nonlinear ordinary differential equations are solved numerically and the numerical solutions to static thermal post-buckling and thermal bending deformation of the sandwich beams with pinned-fixed ends under transverse uniform thermal loads are obtained. Characteristic curves of the critical buckling temperature versus foundation stiffness parameter for the first three buckling modes are plotted and critical thermal buckling modes transition feature are given.
