Abstract

The lock-in infrared thermography technique was adopted to rapidly determine the fatigue limits of two kinds of riveted components, which were both made of 2A12 aluminum alloy and had different magnitudes of interference. The results obtained by the lock-in infrared thermography technique were compared with the existing fatigue limits of 2A12 aluminum alloy, and experimental research based on the staircase method was also carried out. It is shown that the magnitudes of interference and the corresponding initial stresses have important and apparent affections to the results determined by the lock-in infrared thermography technique.
