✦ Synopsis

The relative displacement per unit load of two conjugate points is used as a quantitative indicator of crack extension in plane strain fracture toughness Kic measurements. The necessary displacement data are presented here in dimensionless form for five types of single--edge-crack specimens: three-point bending, pure bending, remote axial tension, and eccentric tension of compact rectangular and tapered varieties. The results were obtained by a boundary collocation method of elastic analysis and are highly precise. * For example, for remote axial tension, the factor is [d log(vyEB/P)/d log(a/W)] which is equal to [(a/W)/ (vyEB/P)] [d(vyEB/P)/d(a/W) ] as in fig. 40 of ref. 1.
