Abstract
Events related to the failure in structures have shown the importance of maintenance. It is known that the vibration control is a very relevant field of study within Mechanical Engineering that seeks an attenuation and inspection of vibrations of a system. The competitiveness of industries is directly linked to investment in process and equipment monitoring. Structural integrity is essential for the analysis of a system to be correct and valid when the vibration analysis has an unexpected response; there is probably a change in this structure. Thus, the primary purpose of monitoring is to previously identify damage such as cracking and corrosion, reducing the risk of catastrophic failure. To detect and quantify the damage, the study of reflected waves and incidents present a good result. Currently, periodic structures are in evidence. They consist of a series of repeated elements connected to the same joints and are present in aircraft, buildings, bridges and even in critical structures. In this context, the current work has the purpose of locating the fault and quantifying it, using the transfer-matrix method that aid in the representation of periodicity.
