摘要：

Hertzian cone cracks formed by indenting brittle solids with a hard sphere have previously been shown to close imperfectly as the indenter load is released; accordingly, there is little tendency for air-formed cone cracks to heal naturally. In the present instance partial healing has been achieved artificially by subjecting residual cone cracks in glass to closure-enhancing treatments. Observations of the crack geometry both during and after loading suggest that healing occurs only at localised regions of intimate contact across the crack interface. Possible mechanisms for the healing process are discussed.
