... The SEM fractographs of the three zones are shown in Fig. CH31.2 to CH31.4 . Zone 1 shows a mixed mode of fracture, consisting of cleavage and intergranular fracture ( Fig. CH31.2 ). Zone 2 is characterized by striations and secondary fissures ( Fig. CH31.3 ). The direction of crack growth is from...

The delamination due to impact will also exhibit more evidence of shear (i.e., hackle formation in the damaged region) as compared to the surrounding area, which will generally have more river patterns indicative of the manually applied, mixed-mode, or mode I tensile loading.

.... This is not the same kind of brittle fracture (i.e., by separation) as generally expected. Slippage can occur if we superimpose some compression load (in one direction) to the hydrostatic pressure. Torsional failure can occur in one of two modes—shear or tension—because the magnitudes of τ max and σ max...
