Systematic Evaluation of Strength Distribution in Dielectric Ceramics through Simultaneous Loading

Abstract

We attempted application of the simultaneous loading system previously proposed by us on dielectric ceramics. Electrical conduction was introduced by means of a conductive coating which does not affect the strength distribution. For fracture determination, a stepwise conduction profile was monitored. In this way, the simultaneous loading system was applied to dielectric ceramics and it demonstrated the same strength distribution as that obtained from conventional measurement. Therefore, this method can be applied to dielectric ceramics as well as to electroconductive materials. It is expected to be advantageous for measurements of strength distribution under extreme conditions of high temperature and pressure.
