“…Two round-robin test programs were organized by ASTM E08.08 Task Group for validating the normalization method in J-R curve testing for high-rate loading conditions [150] and for static loading conditions [151] using C(T) specimens. Further investigations and applications of normalization method were performed by Dzugan and Viehrig [152], Zhu and Joyce [153], Zhu and Leis [154], and Zhu et al [155] using SE(B) specimens for different metallic materials. The results showed that the normalization method can be equivalent to the elastic unloading compliance method and the electric potential drop method under quasi-static and dynamic loading conditions.…”

Stress intensity factor Energy release rate CTOD CTOA J-integral J-R curve K-R curve ASTM standard a b s t r a c tThe present paper gives a technical review of fracture toughness testing, evaluation and standardization for metallic materials in terms of the linear elastic fracture mechanics as well as the elastic-plastic fracture mechanics. This includes the early investigations and recent advances of fracture toughness test methods and practices developed by American Society for Testing and Materials (ASTM). The review describes the most important fracture mechanics parameters: the elastic energy release rate G, the stress intensity factor K, the Jintegral, the crack-tip opening displacement (CTOD) and the crack-tip opening angle (CTOA) from the basic concept, definition, to experimental estimation, test methods and ASTM standardizing practices. Attention is paid to guidelines on how to choose an appropriate fracture parameter to characterize fracture toughness for the material of interest, and how to measure the fracture toughness value defined either at a critical point or in a resistance curve format using laboratory specimens. The relevant ASTM fracture toughness test standards considered in this paper are E399 for K Ic testing, E561 for K-R curve testing, E813 for J Ic testing, E1152 for J-R curve testing, E1737 for J Ic and J-R curve testing, E1290 for CTOD (d) testing, a combined common test standard E1820 for measuring the three parameters of K, J and d, E1921 for the transition reference temperature T 0 testing and the master curve of cleavage toughness K Jc testing, and E2472 for CTOA testing. The effects of loading rate, temperature and crack-tip constraint on fracture toughness as well as fracture instability analysis are also reviewed.

“…The current study focuses on the data from small-scale yielding, high-constraint fracture specimens, in deriving the lower-bound J-R curve. The J-R curve data included in the current study covers a wide range of structural steels with various grades for different applications, comprising of the pressure and reactor vessel steels [37][38][39][40][41][42], pipe and pipeline steels [43][44][45][46][47][48], steels for other structural applications [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65] and weld materials [66,67].…”

For structural integrity analysis of thin walled tubular components such as fuel claddings used in nuclear reactors, knowledge of valid fracture mechanics parameters are required. As axiallycracked thin tubes possess a non-standard geometry from the point of view of specimen fabrication, there is no direct straight forward way to derive their fracture mechanics parameters with known functions as can be done for standard test methods. In the present work, the J-R curve for an axially cracked fuel pin from Indian 220 MWe pressurized heavy water reactor is derived after experimental and analytical derivation of the required parameters and the results are compared with earlier published data for similar material.
