Part of the Fracture Mechanics of Ceramics book series (FMOC, volume 1)


Measurements of the radii of fracture mirrors have been used extensively to analyse glass fracture surfaces. Several investigators including Terao,1 Levengood2 and Shand3,4 investigated the relationship between the fracture stress (σf) and mirror radius (rm). The data are in reasonable agreement with
