Applicability of miniature size bend specimens to determine the master curve reference temperature T0

Determination of reference transition temperature of In-RAFMS in ductile brittle transition regime using numerically corrected Master Curve approach

“…The transition temperature found from test data of 0.2T SE(B) was À123.5°C which is close to the reported values (T 0 = À119°C) obtained for F82H [18,30]. However, this temperature is non-conservative as it has been obtained from non-SSY condition test data.…”

“…It can be realized from Table 5 that the numerically corrected T 0 estimate of À109°C for In-RAFMS is close to the other RAFMs reference temperatures obtained by various methods of constraint correction [18,[28][29][30][31]. The uncorrected data are also shown in Fig.…”

“…Many researchers such as Petti and Dodds [14], Landes and McCabe [16] Mueller et al [17] including Wallin et al [18] has discovered various correction methods to resolve the problem due to constraint loss. In order to resolve the problem of non-SSY condition in small samples, numerical approaches need a model to simulate cleavage phenomenon.…”

Fracture toughness characterisation in the ductile-to-brittle transition and upper shelf regimes using pre-cracked Charpy single-edge bend specimens

“…The scale parameter J 0 may be related to the mean value of J c , J c by J c Z 0:89J 0 (20) As a result, the lower bound toughness is then simply obtained by…”

Probabilistic fracture toughness of a duplex stainless steel in the transition range

“…the most critical temperature range for duplex stainless steels, by means of the weakest link approach developed by Wallin and co-workers [2][3][4], which is at the basis of the ASTM E 1921-11 Standard.…”
