Abstract : Large amplitude free vibrations of an axisymmetric circular plate of orthotropic 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.
