... 6, “Basic Single-Load Fracture Modes,” in this book, ductile fractures are those in which the shear stress exceeds the shear strength before any other mode of fracture can occur. Therefore, the micromechanism of fracture is in the shear direction, but this is not always obvious on macroexamination...
