Bending and thermal buckling of unsymmetric functionally graded sandwich beams in high-temperature environment based on a new third-order shear deformation theory

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.

Automated summary

This paper presents new results on static bending and thermal buckling of sandwich functionally graded beams in high temperature conditions. The use of TSDT eliminates the need for shear correction factors and prevents shear-locking. The study concludes that not all functionally graded structures can perform well under high temperature conditions.
