Main Article Content
The purpose of this study is to introduce an innovative method, the Adomian modified decomposition method, to solve the vibration problem of thin elastic plates. By applying the present method to vibration problem of thin plates, the fundamental and higher frequencies as well as their mode shapes can be obtained easily for common and complicated boundary conditions, including elastic supports. Other benefits of using this method can be realized in terms of rapid convergence, small computational expensiveness and stability in calculation. The significant effects such as effects of boundary conditions, aspect ratios and translational and rotational spring constants, which lead to considerable changes in frequency results and mode shapes, are investigated and discussed.
