dc.description.abstract© 2017 Chinese Society of Theoretical and Applied Mechanics. All Rights Reserved.This paper investigates how crack front curvature affects instantaneous crack size predictions based on the elastic unloading compliance technique applicable to SE(B), C(T) and clamped SE(T) specimens. Relative crack depths (a/W) of 0.2, 0.5 and 0.7, alongside five levels of crack curvature were considered. Crack front was modeled as a semi-ellipse. It was shown that for the same ASTM equivalent straight crack [1] compliance decreases as tunneling increases. Since the maximum crack curvature allowed by ASTM is very restrictive, compliance did not change much within that limit, but if violated, a remarkable deviation may occur. As a step to improve such techniques, a new formulation to determine the equivalent straight crack was developed. The new proposal shows reduced errors on compliance as crack curvature grows when compared to current ASTM proposal.
