Linear thermoelastic buckling and free vibration behavior of functionally graded truncated conical shells

摘要: Abstract In recent years, structures made up of functionally graded materials (FGMs) have received considerable attention for use in high-temperature applications. this article, a finite element formulation based on First-Order Shear Deformation Theory (FSDT) is used to study the thermal buckling and vibration behavior truncated FGM conical shells environment. A Fourier series expansion displacement variable circumferential direction model shell. The material properties are thickness according volume fraction power law distribution. Temperature-dependent considered carry out linear free analysis. shell assumed be clamped–clamped has high temperature specified inner surface while outer at ambient temperature. one-dimensional heat conduction equation across determine distribution thereby properties. addition, influence initial stresses frequency also been investigated. Numerical studies involving understanding role index, r / h ratios, semi-vertex angle as well carried out.
