Buckling and free vibration analysis of functionally graded cylindrical shells subjected to a temperature-specified boundary condition

摘要: Abstract Linear thermal buckling and free vibration analysis are presented for functionally graded cylindrical shells with clamped–clamped boundary condition based on temperature-dependent material properties. The properties of materials (FGM) shell assumed to vary smoothly continuously across the thickness. With high-temperature specified inner surface FGM outer at ambient temperature, 1D heat conduction equation along thickness is applied determine temperature distribution; thereby, distribution made available analysis. First-order shear deformation theory Fourier series expansion displacement variables in circumferential direction used model shell. Numerical studies involved understanding influence power-law index, r/h l/r ratios critical temperature. Free under elevated show that fall natural frequency very drastic mode corresponding lowest when compared mode.
