Description
The Ball-on-Three-Balls-Test (B3B) and the Ring-on-Ring-Test (RoR) were conducted on alumina discs and compared according to Weibull-Theory. Based on experimental results, the influence of various intermediate layers on strength measurement was evaluated. To support these findings, Finite-Element-Analysis was conducted to analyze the effects of deviations from ideal loading conditions for both tests. The influence of friction between sample and fixture and the effects of an inhomogeneous load distribution on the maximum stress were investigated. These numerical findings are supported by fractography.
