Abstract

According to the randomization method of deterministic equation, a p-J_R-Δ fracture curve equation is established. From this fracture p-J_R-Δa curve and fracture passivation curve, fracture critical value (J_1C)_p with the reliability level of p may be obtained. By means of fracture testing principle, fracture (K_1C)_p can be derived from (J_1C)_p. Then the reliability method to determine fracture threshold value ΔK_th is presented. After the treatment of test data, some important results are obtained. From the statistical test, it is validated that fracture threshold value ΔK_th follows the normal distribution.
