Detection and Localization of Cracks in Composite Beams Using Fractal Dimension-Based Algorithms : a Comparative Study

In the presented study the possibility of application of algorithms, which based on the estimation of fractal dimension for the problems of damage detection in localization in composite structures was considered. Four algorithms were compared with respect to accuracy of detection and localization of damages in a composite beam and unambiguity of obtained results. Thanks to the low complexity of the computational algorithms, which based on fractal dimension they could be successfully applied in the diagnosing and monitoring real-time systems and even implemented in hardware.
