✦ Synopsis

Non-linear dynamic responses are analyzed for a #exible spinning disc with angular acceleration. Based on the Kirchho! plate theory and the von Karman strain theory, non-linear equations of motion are derived, which are coupled equations between the radial, tangential and transverse displacements. The equations of motion are discretized by using the Galerkin method. From the discretized equations, the dynamic responses are computed by the generalizedtime integration method. The analysis results show the e!ects of angular acceleration on the dynamic responses.
