Abstract

A simultaneous loading system in which fracture stress distribution was substituted by fracture time distribution was previously proposed. However, this method could only be applied to electroconductive materials. In the present study, application of this simultaneous loading system was attempted on insulating materials to which electrical conduction was introduced. A thin gold film is coated on titanium dioxide ceramics to introduce electrical conductivity in them. The average strength and the Weibull modulus were not affected by the conductive coating. It is concluded that our simultaneous loading system can be used in the evaluation of dielectric ceramics and the equivalent strength distribution is obtained.
