... 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. Scanning electron microscopy...

There is usually a need to provide some test data to designers in addition to the modulii and ultimates derived from micromechanics data. Designers have been consistently more confident with data...
