Abstract

A new inspection method is proposed to detect fatigue crack on steel bridges based on stress concentration features. The relationship between stress and temperature of the component is built theoretically. Fatigue cracks can be located by calculating distortion stress based on detection of temperature distortion of the component using an infrared thermal imager. As an example, consider a plate with a hole. Relationship between stress and temperature of the hole-edge spots is studied under cycle loads. The results show that the temperature of left/right spots decrease and top/bottom spots increase when t=0.05 s, and the temperature of left/right spots increase and top/bottom spots decrease when t=0.15 s. These agree with the theoretical result, and the mode test results show feasibility of the proposed method.
