13th International Conference on Fracture June 16–21, 2013, Beijing, China -8- θ4 1.0000 0.9500 0.89050.9374 θ5 1.0000 0.6889 1.49182.1655 θ6 1.0000 0.9771 0.99961.0231 The result of the TMCMC-slice method is satisfactory, only the identified values of θ3 and θ5 are deviate from the actual values, but the corresponding standard deviation (s.d.) and coefficient of variance (c.o.v.) are also large, which denote that the results have lower credibility. Then the sample updated trajectory and probability density distribution are respectively used to further analysis the performance of TMCMC-slice, as shown in Fig. 5 and Fig. 6. Figure 5.
