Abstract A high time resolution thermovision and an infrared detector withthe diameter of 20mm were used to detect the temperature distribution on the sur-face of samples which rotated and bending fatigued at high speed. The relation be-tween infrared radiation and local fatigue damage has been determined. A new non-destructive testing method for fatigue damage has been given.

Key words: fatigue crack infrared thermography nondestructive testing
