Shear lips, zero isoclinics, and fracture / L.P. Trudeau, Physical Metallurgy Division. : M38-1/201-1969E-PDF
"Examination of "shear lip" contours formed in the process of fracture under tensile stress shows that they regularly start at 60 degrees to the flat part of the fracture. These well-defined contours might be expected to have a mechanical cause that predicts their form more closely than the common assertion that they are 45-degree shear fractures. It is suggested that the "shear lips" are actually zero isoclinic contours characterized by zero shear. This hypothesis is physically plausible because the oblique part of the fracture could occur with purely normal displacements in the same way as the flat part of the fracture is formed. An equation for the elastic zero-isoclinic contour is presented, and also experimental evidence,in support of the proposal, obtained from tensile tests and tests with birefringent plastic on steel crack-notch toughness specimens"--Abstract, page i.
