FLEXURAL STRENGTH OF ALUMINA CERAMICS: WEIBULL ANALYSIS

In this paper, flexural strength, fs, of cold isostatically pressed (CIP) high purity alumina ceramics was determined by the three-point bend test. It was found that flexural strength shows a large variation and can be described by a two-parameter Weibull distribution function, with the scale parameter 0, and the Weibull modulus m. These parameters were determined by the linear regression using the measured values of fs. It was found that the measured flexural strength, fs, of alumina ceramics follows the Weibull distribution. The flexural strength values were found to range from 266.7 to 357.5 MPa.
