The maximum fracture velocity of silicon

  • J. H. Greenwood


A “Wallner Line” effect on the fracture surface of silicon is described and is used to determine a maximum fracture velocity of (3800 ± 400) m/s or (0.75 ± 0.07)vt. The mirror energy of silicon is also measured. The values are compared with those for glass and other materials and are shown to be consistent with a solid whose crack branching angle is restricted to 70‡.
