| Abstract: | By accurately considering the axial extension and transverse shear deformation in the sense of theory of Timoshenko beam,geometrically nonlinear governing equations for functionally graded sandwich beams subjected to thermal loads were formulated.By using a shooting method,the obtained boundary value problem of nonlinear differential equations was numerically solved;and thermal buckling and post-buckling responses of transversely non-uniformly heated FGM Timoshenko sandwich beams with fixed-fixed ends were ... |
