Abstract
The bending analysis of sandwich functionally graded (FG) beams under temperature circumstances is performed in
this article utilizing Navier's solution-based parabolic shear deformation theory. For the first time, a comparative study has been
carried out between the exponential and sigmoidal sandwich FGM beams under thermal conditions. During this investigation, temperature-dependent material characteristics are postulated. Both symmetric and unsymmetric sandwich examples have been studied. The effect of gradation law, gradation coefficient, and thickness scheme on beam behavior has been thoroughly
investigated. Three possible temperature combinations at the top and bottom surfaces of the beam are also investigated. Beams
with a higher proportion of ceramic to metal are shown to be more resistant to thermal stresses than beams with a higher proportion of metal.
