摘要: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. And critical thermal buckling modes transition feature are given. With the increasing foundation stiffness parameters, the corresponding physical meaning and the curves of relationship between temperature parameters and the boundary force and moment is given.
