“…Garwood [225] was among the first and showed that an experimental J-R curve derived from the center-cracked panel was appreciably steeper than one obtained from a three-point bend specimen, but the initiation toughness values were essentially identical for these two geometries. Similar constraint effects on J-R curves for ductile materials under plane strain conditions were observed widely by many other investigators, including McCabe et al [226], Towers and Garwood [227], Eisele et al [228], Hancock et al [229], Joyce et al [230][231][232], Wardle [233], Lam et al [234], Neimitz et al [235], and Shen et al [236]. All experimental results showed that deeply cracked, bending loaded standard specimens result in lower J-R curves, and shallow cracked, predominantly tensile loaded nonstandard specimens lead to higher J-R curves, with the plane strain initiation toughness J Ic being nearly independent of these specimen geometry and loading mode effects.…”

“…Joyce and Link [231,232] showed that three-point bend SE(B) specimens can be tested over a wide range of a/W ratios with the resulting J-R curves demonstrating a wide range of effective toughness. Since this geometry is a relatively easy one to test, SE(B) specimens with various a/W ratios are often used to investigate the constraint effect on J-R curves for ductile materials, with the fracture tests following the procedures specified in ASTM E1820, except for the much larger range in a/W ratios utilized.…”

“…In general, the parameter Q can effectively describe the constraint effect on the crack-tip field for different geometries under a variety of deformation levels. Accordingly, Q has been used extensively to quantify the constraint effect on the fracture toughness parameters J c and J Ic , see O'Dowd and Shih [262], Nevalainen and Dodds [265], Joyce and Link [231,232], and Gao and Dodds [266].…”

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 FAD approach can also be modified to include the additional fracture parameter [39][40][41]. It is expected that the constraint-based fracture methodologies would provide more realistic predictions of the instability crack length.…”

“…But for J-R curve, most of the studies report no discernible trend. Only Joyce and Link 11,12) have reported higher J-R curve with increasing a/W ratio in the ranges of a/WϽ0.4 or a/WϾ0.75. Table 2 summarizes the observed trend of variation of J IC with thickness.…”
