The natural frequencies of cracked and uncracked clamped-clamped beam are measured using single-input multi-output (SIMO) based experimental modal analysis (EMA). The crack present at various locations on the beam is generated using wire cut electro discharge machining process (WEDM). The crack is assumed to be transverse and one dimensional partial cut of a beam and is modeled as equivalent elastic rotational spring. Using Euler-Bernoulli beam theory, a closed form solution of the structural/mechanical member is presented. The measured frequencies of the beam with crack are utilized to identify crack location and its severity by the frequency-based approach as well as genetic algorithm (GA) based intelligent search for the same test points. GA is executed to find global minima of a fitness function that is a function of measured and theoretical frequencies of the cracked beam. The results of predicted crack location and its severity by both the approaches are compared and found to be good agreement with the actual crack parameters.
