To avoid mechanical resonance and fatigue damage in engineering designs, it is crucial to predict and understand the responses of structure due to high frequency vibration and noise. This paper presents high frequency vibration analysis of Mindlin plates using spline Ritz method. To demonstrate an accuracy and convergence of the present method, some numerical examples are solved and the results are compared with those obtained by analytical method and other numerical methods. We also demonstrate the present method for high frequency vibration analysis by providing accurate frequencies for Mindlin plates vibrating in the first 5000 modes.
