Rapid Measurement of Fatigue Behavior of Welded Joints Using the Lock-in Infrared Thermography
Year: 2012
Type: conference-paper
Abstract: Considering the practical operating situations, the lock-in infrared thermography was used to rapidly determine the fatigue perfomance of welded joints subjected to a highly fixed mean stress.The results obtained by the lock-in infrared thermography were compared with the traditional results.Good predictions indicated the potential ability of the lock-in infrared thermography in investigating inhomogeneous welded joints.It is shown that the application of the lock-in infrared thermography as a non-destructive and non-contact method to predict fatigue behavior of materials and to detect the occurrence of fatigue damage for safety evaluation was suitable to consider the practical operating situations.
