Large amplitude vibration of functionally graded circular plate
Based on the nonlinear plate theory, axisymmetric large amplitude vibration of a circular plate made of functionally graded materials (FGM) is investigated. The material properties of plates are assumed to be graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of the constituents, and to be temperature dependent Existence of harmonic vibrations is assumed and then Ritz- Kantorovich method is used to convert the dynamic Von Karman equations to a set of nonlinear ordinary differential equations. Finally, a shooting method is employed to solve the resulting equations. Effects of amplitude, material constant, thermal loads and temperature-dependent properties on the vibration behavior of FGM plate are discussed in detail.
