Popis: | An iterative method to determine the location and size of flaws using dynamic response measurements is presented. The solution procedure combines frequency-domain problem solving methods (deconvolution and the spectral element method) with a stochastic iterative search technique based on a genetic algorithm. Experimentally measured acceleration and strain responses from example structures are used to verify the method. |
