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