Thursday, May 2, 2019

by Steven Schrock, PhD

A computerized process of determining fatigue cracks using video, designed by Dr. Jian Li, this method has the potential to improve the accuracy and speed of performing these inspections. By automating the process, there is also the possibility of lowering inspection costs. The method involves taking a short video stream of a structure in a crack-prone area under repetitive loading, and processing the video through a computer. According to Dr. Li, the method can also be used in other applications, such as detecting localized slippage or the loosening of structural components.
