“…Especially in 3-point bend specimens it is possible to determine experimentally the apparent (plastic or overall) rotational factor by recording simultaneously the clip-gauge displacement and the load-line displacement [17][18][19]. Especially below the general yield load, FGv, the method seems to be not very accurate, because "... if (F/Fcv) < 0.9 the re-values calculated are irregular and most of them are greater than 0.5" [17].…”

“…Especially below the general yield load, FGv, the method seems to be not very accurate, because "... if (F/Fcv) < 0.9 the re-values calculated are irregular and most of them are greater than 0.5" [17]. Beyond general yield most re-values lie between 0.4 and 0.5 [17][18][19]. They are increasing slightly with increasing %-values, probably due to crack extension.…”

A procedure for estimating theoretically the physical crack-tip-opening displacement (COD) for bend and CT-specimens is developed. The theory relies on the Irwin model of the plastic zone and on other well-known fracture mechanics relationships. Relationships between the physical COD and the conveniently measured crack mouth opening displacement are given in terms of rotational factors. Based on such theoretical considerations, on experimental results from literature, and on the authors experimental results it is concluded that the formula stated by the British Standard Test Method for measuring the critical COD overestimates the physical COD below general yield of the testpiece. An improved procedure for estimation of the physical COD is recommended.
