| Abstract: | In this paper,a new discrete method is proposed to calculate the characteristics of free vibration of plates with non-uniform thickness.The experimental methods of laser holography interferometry are introduced to verify the accuracy of the numerical solution.The experiments have been done for plates with uniform,non-uniform thickness and with a hole defect.The analytical results have been compared with experimental results.From above experimental results analysis,it is shown that the proposed discrete method has enough convergence and accuracy. |
