Beretta et alii, Frattura ed Integrità Strutturale, 41 (2017) 269-276; DOI: 10.3221/IGF-ESIS.41.36 273 Figure 4 : Precision of SIF calculation depending on the crack length and the dimension of the regression region for the SENT specimen. The regression based only on the K term is not accurate for most of the crack lengths investigated, and it gives accurate predictions only for small regression regions d<0.05mm which requires high DIC resolutions. The most accurate solutions are given by the 3-terms regression.
