Thermoelastic buckling and vibration behavior of a functionally graded sandwich beam with constrained viscoelastic core

摘要: In this article, buckling and vibration behavior of a functionally graded material (FGM) sandwich beam having constrained viscoelastic layer (VEL) is studied in thermal environment by using finite element formulation. The FGM assumed to be clamped on both edges. properties are thickness direction according volume fraction power law distribution. Temperature dependent stiff shear modulus considered carry out analysis. Numerical studies involving the understanding effect index, core ratio temperature as well has been carried out. addition influence natural frequencies loss factors have examined for beam.
