13th International Conference on Fracture June 16–21, 2013, Beijing, China -3- 4. Results 4.1. Thermal results Figure 2 shows the entire temperature recording versus the number of cycles on the specimen surface during the test. As previously published [4], the temperature has a quick increase at the beginning of the test and tends progressively towards an asymptotic until the fatigue crack growth in mode II leading to the failure . Higher is the stress, higher is the temperature level. Figure 2: Temperature evolution versus number of cycles From these data, the temperature profile (Figure 3) along the specimen width was extracted for the 168 latest pictures captured by the camera, that is to say from 3.2086.107 cycles to 3.2153.107 cycles (number of the cycles at the failure).
