This paper presents a methodology for analyzing free flexural vibration of rectangular plates having single linear cracks. The methodology is based on the Levy method and boundary element method. Rectangular plates with simply supported boundary conditions along all four edges are used to illustrate the solution procedure. Natural frequencies obtained using the proposed methodology were compared with those obtained using ANSYS and those available in the. The procedure described in this paper methodology can be easily extended to plates with other boundary conditions with the aid of the method of superposition.
