Abstract

The strength values obtained during six series of bend tests on three monolithic ceramic materials have been evaluated statistically. Statistical mapping procedures were used to check whether a Weibull distribution fits the strength data. Where this has been found to be the case, the value of the Weibull parameters, determined according to different evaluation methods, fall within each other's confidence range. The values of the modulus m and of the characteristic strength sigma(0) of the two-parameter distribution can differ strongly from the corresponding values in the three-parameter distribution. Where the data cannot be fitted to a Weibull distribution, the occurrence of more than one flaw population is indicated.
