The nature frequencies of the cantilever beams with various crack locations and depths are accurately obtained by means of wavelet finite element methods, and then surface-fitting technique is employed to approximate frequency response functions. Measured natural frequencies are used in a crack detection process and the crack location and size can be identified through using genetic algorithm. The experimental results verify the validity of the method, which provides a powerful evidence for practical application.
