In this paper, we present new results of static bending in high temperature and thermal buckling of sandwich FG beam based on new third-order shear deformation theory (TSDT) and finite element formulations. In the case of static bending, we assume the sandwich beam placed in a high-temperature environment for a long time, and so that temperature distribution is uniform across the beam thickness. In the case of thermal buckling, we focus on temperature-dependent material properties solution (called the TD). Using this TSDT, the analysis does not need any shear correction factors and has no shear-locking. The results show that not all FGMs could process similar to mechanical behaviors and have the ability to perform at high temperature.} }
