Abstract
Special features of resistance to Vickers indentation exhibited by ZrO2 ceramics and crystals are investigated. The relation between their behavior in indentation and deformation in static bending is investigated. The anisotropy of lateral cracks in the (001) plane in partially stabilized ZrO2 crystals is shown to correspond to the anisotropy of their elasticity moduli. New variants of the formulas for evaluating the crack resistance in indentation of zirconia materials, which obey Hooke's law until the moment of failure, are presented.
