Fatigue Crack Detection by Ultrasound Infrared Thermography

摘要：

This paper describes the application of ultrasound excited infrared thermography. In this technique, an ultrasound wave passing through a material with mechanical discontinuity such as a crack or disband causes temperature raise of that due to internal friction or thermo-mechanical effect and the localized heating area is visualized with infrared camera. In this paper, the detection ability of the technique in fatigue damage of metal materials has been characterized according to crack width.
