13th International Conference on Fracture June 16–21, 2013, Beijing, China -8- Figure 2. Normalized dynamic a) mode-I and b) mode-II SIFs for 1 ln(2), ln(3), ln(5) gh Figure 3. Normalized dynamic a) mode-I and b) mode-II SIFs for 1 ln(0.5),ln(0.333),ln(0.2) gh Figure 4. Normalized dynamic a) mode-I and b) mode-II SIFs for 0 1 / 5,10,15, 20 h h and 1 ln(2) gh The effects of the thermo-mechanical coupling on the normalized dynamic mode-I and mode-II SIFs can be observed in Figs. 6 and 7. In this case, the thermo-mechanical coupling parameter (5) is taken as 0.133 and 0.3 , which correspond to the previously used material parameters with the reference temperatures 0 100 T and 0 225 T , respectively. With the increase of the coupling
