N2 - Subsurface cracsk in ceramics introduce by Vicker indentation were examined by acoustic microscopy. The average length and initiation probability of subsurface lateral cracks were measured from acoustic images and found to depend more significantly on the material used than those of surface breaking radial cracks. The ratio of fracture toughness Kcfor lateral fractures to fracture toughness Kic for radial fracture also varied depending on the materials used. These results revealed the difference in basic mechanisms of lateral and radial fractures in ceramics.
