摘要：

An analytical study is presented on the flexural buckling of sandwich beams considering thermal-induced non-uniform cross-sectional properties. The formula for determining the buckling loads of sandwich beams under a linearly varied non-uniform temperature distribution scenario, both with and without considering the influence of transverse shear deformation, is derived. The effects of local reductions in Young's modulus and shear modulus on the flexural buckling of sandwich beams are discussed. The obtained results demonstrate the importance of considering non-uniform cross-sectional properties and associated shear effects in the buckling analysis of sandwich beams when they are exposed to a thermal environment.
