The residual stress field is initiated in the vicinity of sharp indent (Vickers) too. Also to the studying of the residual stress field the special identation technique was applied. Identation technique is a reliably technique, which makes possible to determine the set of mechanical properties of ceramics (brittle) materials. Some cracks are developed near the identation cavity and their parameters reflect except the fracture toughness value and response to the repeated loading the level of residual stresses. Two types of technical ceramics (Al₂O₃ and Si₃N₄ ) with a different level of mechanical properties are the subjects of present study.
