| Popis: | A series of experiments are performed in the ductile to brittle region on TPB specimens with different thickness and a/W ratio and a variation of T0 is obtained, which indicates constant dependent on T0. An attempt is made to correlate T0 with Q-stress, T-stress and Triaxiality ratio to count for the constraint loss. Both the average value and also the maximum value of the finite element parameters are considered to predict T0 at different constraint label and compared with the experimental results |
