The impact damage of brittle ceramics has recently been studied from the Hertzian-fracture-surface-identation viewpoint. These studies have identified the projectile (indenter) and material properties which affect the material's impact resistance and strength after impact or indentation. This approach is used to analyze the strength after impact (sigma/sub fai/) for a series of binary alkali-silicate glasses subjected to an air abrasion blast of granular SiC. Results of these studies show that the response of brittle ceramics to multiple projectile impacts such as abrasive grains, is related to their response to single Hertzian indentations and that the fracture toughness of brittle ceramics is of importance to its resistance to impact damage.
