A simple model based on realistic assumptions for determining the fatigue crack propagation rate is presented. It relies on the measurement of the temperature evolution around the crack tip thermographically. The approach is capable of predicting crack propagation speed in both low- and high-growth rates. Results can be used to determine the stress intensity factor.
