Contact Damage and Damage Tolerance of Dental Ceramics
Surface and subsurface contact damage in dental ceramics and the influence of microstructure on damage tolerance were investigated in this study through indentation methods. The dependence of the damage tolerance on common materials properties was discussed. A simple expression to estimate quantitatively the damage tolerance via basic material parameters, based on the features of damage tolerance and fracture mechanics is confirmed. And the residual strength of damaged specimen was measured via three-point bending tests.
