Metal structures under fatigue as a result of loading and harsh environmental conditions are prone to developing cracks. Crack detection is an important area of Structural Health Monitoring (SHM).
For example, rivets and other joints often bear a high concentration of stress, which can lead to crack initiation and propagation as a means of relieving the stress. Sometimes flaws introduced during manufacturing become cracks during operation of the structure.
In many cases, it is impossible to detect a crack visually, either due to the inaccessibility of the region or the microscopic size of the crack. Such a hidden crack can decrease the strength of the structure, resulting in ductile or brittle failure. At a minimum, this can lead to significant downtime of the structure; at a maximum, this can lead to injury or death. Early detection is the best way to prevent inconveniences and catastrophes.
