... and may not all be analogous fractures. In overload, steel wire ropes typically exhibit classic cup-and-cone ductile overload features. Fatigue is the most important fracture mode in wire ropes because it generally appears at a fraction of the rated strength, below the yield strength, and often...

... that was obtained during the evaluation of a carbon steel (0.25% C, 0.63% Mn, 0.27% Si) casting. Instead of the usual cup-and-cone tensile fracture, the surface was at an angle, approximately 45°, to the tensile axis and was rather rough.

... a slant (shear) fracture at about 45°. This 45° slant fracture is often called a “shear lip.” Many fractures are flat at the center, but surrounded by a “picture frame” of slant fracture. An example of this behavior is to be found in the familiar cup-and-cone fracture of a round tensile test bar...
