Abstract: An approximate method based on the Green function for analyzing the free vibration of irregular-shaped plates is proposed. In this paper, the irregular-shaped plates are such plates as sectorial plates, triangular plates, circular plates, elliptical plates, or the other polygonal plates which are not uniform rectangular plates. It is shown that these irregular-shaped plates can be considered finally as circumscribed equivalent rectangular plates by adding some parts and the added parts are extremely thin or thick according to the boundary conditions of the original plates. Therefore the free vibration analysis of any irregular-shaped plate can be replaced by the free vibration analysis of the equivalent rectangular plate with non-uniform thickness. For various types of irregular-shaped plates, the convergency and accuracy of numerical solutions by the proposed method are investigated.
