Large Amplitude Free Vibrations of Axisymmetric Orthotropic Circular Plate

摘要

Large amplitude free vibrations of an axisymmetric circular plate of orthotropic material have been investigated. Generalised field equations in the dynamic case for such a plate have been derived (in the von Karman sense) in terms of displacement components. Time-periods for linear and nonlinear vibrations have been compared and corresponding results for isotropy have been deduced. Some numerical results for the ratio of time-periods vs. non-dimensional amplitudes have been presented in tables.
