Abstract

The lock-in infrared thermography technique was proposed to determine the fatigue limit of 2A12 aluminum alloy riveted component rapidly. The results obtained by this technique were compared not only with those obtained by interpolating the existing fatigue limits of the same material under different stress concentration coefficients and different stress ratios, but also with the results obtained by the conventional staircase method. It was verified that for conventional riveted component of which the magnitude of interference was not too large, the lock-in infrared thermography technique can be applied to rapidly determine the fatigue limit of metal riveted structure with multiaxial stress at the fatigue dangerous position.
