On the Rapid Determination of 45# Steel Fatigue Behavior Based on Infrared Thermography
|
Abstract:
As a non-destructive, real-time and non-contact testing technology, infrared thermography is widely applied in fatigue research area. This new method solves the problems of traditional test method, such as long cycle of experiment, huge amounts of specimen and high cost. Measurement of temperature variation on surface of 45# steel was carried out, the fatigue limit was established by rapid measuring method, and fatigue life equation was obtained by constructing relation between the accumulated plastic work and the plastic temperature rise.
