Infrared imaging of defects heated by a sonic pulse
High-frequency pulsed sonic excitation is combined with an infrared camera to image surface and subsurface defects. Irreversible temperature increases on the surface of the object, resulting from localized heating in the vicinity of cracks, disbonds, or delaminations, are imaged as a function of time prior to, during, and following the application of a short pulse of sound. Pulse durations of 5...

متن کاملCrack growth induced by sonic IR inspection
We have developed an experiment to study the propagation of laboratory synthesized fatigue cracks under various controlled conditions during Sonic IR inspection. The experiment provides for good repeatability in testing. The parameters of interest include the initial crack length, load history (stress intensity and load ratio) during crack generation, geometry of the crack, material and also th...
متن کاملDefect Detection within a Pipe Using Ultrasound Excited Thermography
Thermal wave infrared imaging for detecting defects in a material has been carried out with high-power ultrasonic sources. An early example of this was the work by Mignogna et al, who utilized a high-power ultrasonic heating of a material, coupled with an imaging by means of an infrared (IR) camera [1]. The time scale for their IR images was several seconds after the application of an ultrasoni...
متن کاملFatigue Crack Monitoring via Load-differential Guided Wave Methods
Detection and localization of fatigue cracks is an important application for inspection and monitoring of civil, mechanical and aerospace structures, but assessment of such damage via ultrasonic guided waves can be problematic when cracks are tightly closed in the absence of applied tensile loads. Proposed here are load-differential methods, which compare signals at one load to those at another...
