摘要：
An analytical relationship between the stress intensity factor and temperature rise for a moving crack tip is proposed. Comparison of the predictions with experimental results shows good agreement in both trend and magnitude. The results reveal the potential of applying theromographical technique for assessing the behavior of crack growth.
