Abstract: The dynamical equations of thin elastic plates in large overall motions considering theeffects of geometric non-linearity and coupling deformation are obtained in this paper, and whicheffects to the dynamics of this system are analyzed. The plots of phase plane and time historyin case of considering geometric non-linearity and coupling deformation and only considering geometric non-linearity are shown in Fig.2 and Fig.3 respectively, and the plot of displacement oftransverse vibration is shown in Fig.4.
