| Abstract: | The fracture toughnesses of high value were studied from both theory and experiment, which were from standard samples and were not satisfied with the effective condition of J integrate value. After analyzing the effective of J integrate, the dimensions of samples, the conception of J integrate and J R resistance curve, it was concluded that these high values of J integrate were worthy of the theoretical studies and engineering applications. |
