Thermal — Vibration Method of Crack Detection
Source abstract
Abstract
We have calculated the amount of heat generated by plastic deformation at fatigue crack tips, and evaluated the size of the temperature rise zone in the structure. The diameter of this zone reaches up to ten crack sizes, and therefore an infrared camera can easily and efficiently detect even small fatigue cracks.
