Although many workers have attempted to explain the low strength of glass in terms of Griffith's concept, a completely satisfactory solution is still not evident. It is Web"Griffith flaws". These flaws are assumed to be randomly oriented in all directions in the material. The propagation may be self-symmetric or oblique. These criteria are especially suitable for use with the finite element method insomuch as the necessity to evaluate crack tip stresses is eliminated. Assuming the stress field to be homogeneous ...
