Notes:
Based on compliance testing of a straight-notch compact tensile (SN-CT) or a single edgebending (SEB) specimen, this paper present a formula with increment form to calculate plastic part ofJ-integral, two formulas for a SN-CT specimen and a SEB specimen to transform crack mouthopening displacement (CMOD) v0 to the crack opening displacement (COD) q along load line, andsimplified formulas to estimate crack length a and effective young’s modulus E. Furthermore, therelation between v and q of the SN-CT specimens of 45 steel and SEB specimens of 30Cr steel wereinvestigated. The results show that the formulas to describe the relation between the ratio v/q and thedimensionless crack length a/w of the specimens accord with the testing results better
