Abstract

The effect of thickness deviation on the apparent strength distribution through simultaneous loading measurement was estimated. Some thickness deviations were generated by computer simulation. An apparent strength was calculated from the intrinsic strength of a sample and thickness difference taking into account of the sample setup of the simultaneous loading measurement. For a hundred samples with thickness deviation which accords with a normal distribution, the apparent strength distribution was calculated based on Weibull statistics and compared to the ideal one. Almost equivalent strength distribution shape was proved to be obtainable from samples with standard deviation of thickness deviation up to 6.5 μm in the case of titanium dioxide ceramics. This critical thickness deviation was larger than 1 μm for all ceramic materials calculated, which could be controllable using a micrometer.
