摘要: Free vibration analysis of functionally graded curved panels is carried out using a higher-order formulation. A C0 finite element formulation used to carry the analysis. The consists nine degrees freedom per node with terms in Taylor's-series expansion, which represents transverse cross-sectional deformation modes. includes Sanders’ approximation for doubly shells considering effects rotary inertia and shear. realistic parabolic distribution shear strains through shell thickness assumed use correction factor avoided. Material properties are be temperature independent direction according simple power-law volume fractions constituents. Heat conduction between ceramic metal constituents neglected. accuracy validated by comparing results those available literature. Effects panel geometry parameters boundary conditions studied.
