Summary

Hertzian fracture tests were conducted on sintered α-silicon carbide, partially-stabilized zirconia and other ceramics by using tungsten carbide spherical indenters. The influence of the indenter diameter, specimen surface conditions, and loading rates on the fracture strengths are discussed. The Weibull statistical treatment of brittle fracture seems to provide very good agreement with the experimental data. The interfacial friction effects due to elastic moduli mismatch between indenter and specimen seem to influence the strength behavior and the distribution parameters considerably.
