“…After that, methodology of crack identification, which employs the natural frequencies obtained by the forward analyses, is detailed. Then, several cracked beam scenarios are considered for discussing the results that are verified using the natural frequency ratios obtained by both the commercial finite element package (ANSYS©) and some experiments given by Kim and Stubbs (2003), Mazanoglu and Sabuncu (2012), Ruotolo and Surace (1997). Finally, achievements and shortcomings of the methods are clearly stated.…”

“…Their method reveals quite satisfactory results provided proper initial guesses are made for convergence of the solution. Ruotolo and Surace (1997) propose a solution procedure employing a genetic algorithm and the results of the finite element model for the detection of multiple cracks in beams. Krawczuk (2002) uses the wave propagation approach combined with an iterative searching strategy including two methods for damage detection in beam-like structures.…”

“…They expressed the changes in dynamic behavior as a function of crack location and extent. Ruotolo and Surace (1997) studied the inverse problem of the crack detection of beam structures utilizing natural frequencies and mode shapes. They formulated the crack detection process (estimating the location and extent of cracks) as an optimization problem, and solved it by genetic algorithm when the number of cracks was known.…”

“…But they indicated that the obtained results show that the procedure developed works effectively only for measurement errors not exceeding 7%. Ruotolo and Surace [4] proposed to identify multiple cracks by using the inverse problem as an optimization task solved by means of a genetic algorithm. They validated this damage assessment technique by considering both simulated and experimental data and demonstrated that this method permits assessment of the number of cracks induced on the beam and can estimate the crack positions and depths with satisfactory precision.…”
