This paper presents a comprehensive review of methodologies and technologies in the domain of dynamic vibration of cracked structures. At first, the developments of work till date in the area of dynamic vibration of various structures are discussed. In the second phase, different methodologies are described with regard to the analysis of faulty structures. The methodologies mainly consist of energy methods, finite element methods, fuzzy inference techniques, neural networks, neuro-fuzzy adaptive techniques and genetic algorithms used for identifying the intensity and location of cracks. It has been found that, apart from conventional methods, artificial intelligence methods can be applied efficiently and smartly to detect faults in various dynamic systems.
