Abstract

This paper presents new results of static bending in high temperature and thermal buckling of sandwich functionally graded beam based on new third-order shear deformation theory (TSDT) and finite element formulations. We assume that the sandwich beam placed in a high-temperature environment for a long time, and so that the temperature distributions uniformly across the beam thickness and material properties are temperature-dependent. Using this TSDT, the analysis does not need any shear correction factors and has no shear-locking. The results show that not all functionally graded structures could process similar to mechanical behaviors and have the ability to perform in high temperature.
