Description

The problem of fracture from cylindrical cavities in brittle materials has been analyzed. The analysis is based on the conditions required to extend cracks that pre-exist at the cavity surface. It involves the combined use of fracture mechanics and statistics solutions for crack extension in the concentrated stress field around the cavity. The general pertinence of the approach is substantiated by experimental studies of fracture from cavities in polycrystalline alumina.
