Once initiated, the fatigue fracture can propagate by high stresses and low cycles or by low stresses and high cycles. The final rupture may have characteristics of brittle and/or ductile fracture modes, depending...

Therefore, the micromechanism of fracture is in the shear direction, but this is not always obvious on macroexamination. The surface...

Fractures accompanied by gross deformation (ductile fracture) are caused by one of three possible failure mechanisms: monotonic ductile overload, very low cycle fatigue, or stress rupture. In contrast, fracture in the absence of gross deformation (brittle fracture) is caused by either: (1) high...
