【 摘 要 】

In the present work aims the free vibration analysis of functionally graded material (FGM) skew plates. Kinematics equations are based on the first order shear deformation theory and a four noded rectangular element is used to mesh the plate geometry. Properties of FGM (Stainless steel and Alumina)material constituents of the plate are considered to be as position and assumed to vary along the thickness direction according to a simple power law. Rectangle plate displacement components are renovated into skew plate geometry by suitable transformation rule. The effects of power law index and boundary condition on natural frequency parameters of FGM skew plates are reported based on FOSD. The related results are discussed briefly. Results are generated for vibration analysis of the FGM skew plate, which may be implemented in the future research involving similar kind of problems.
