Closed-Form Solutions for Laminated Composite and Sandwich Beams Loaded by Temperature Field

Flexural Analysis of Thermally Loaded Symmetric Sandwich Beam

“…This stress does not show significant variation under sinusoidal and uniform thermal loads for various aspect ratios. The results of normal stress obtained by the present theory (HBT) are almost identical with those of parabolic shear deformation theory (PSDT) presented by Kulkarni and Ghugal (2020) under sinusoidal and uniform thermal loads. The through thickness variations of these stresses under sinusoidal and uniform thermal loads are shown in Figs.…”

“…Transverse Displacement   w : The results of transverse displacements under sinusoidal and uniform thermal load obtained by the present theory are shown in Table 1. The results of transverse displacement obtained by the present theory (HBT) are in good agreement with the results presented by Kulkarni and Ghugal (2020). This shows that the present theory is suitable for thick and thin sandwich beams.…”

“…  In-plane Displacement   u : The results of in-plane displacement obtained by the present theory are shown in Table 1 and are in good agreement with parabolic shear deformation theory (PSDT) and sinusoidal shear deformation theory (SSDT) presented by Kulkarni and Ghugal (2020). The present theory shows a significant change in in-plane displacement when aspect ratio changes from 4 to 100 under sinusoidal and uniform thermal loads.…”

“…In the literature, the sandwich beams subjected to mechanical load are analysed by various researchers. Recently, Kulkarni and Ghugal (2020) presented the analysis of simply supported sandwich beams subjected to linear thermal load across the thickness of the beam using an equivalent single layer theory. The review of current trends in theoretical development, new designs and modern applications of sandwich structures was presented by Birman and Kardomateas (2018).…”

“…The thermal displacements were evaluated under linear thermal load. A unified theory was presented by Sayyad and Ghugal (2020) to study the buckling response of functionally graded sandwich beam. This theory was built upon a classical beam theory.…”
