Abstract
In this paper fracture toughness, K IC, of CVD SiC ceramics was determined by measuring the crack lengths associate with a Vickers indentation. It is well known that the measured fracture of brittle ceramics shows large variability. Therefore, the probabilistic characteristics of fracture toughness were analysed by a two-parameter Weibull distribution function, with scale parameter, K0, and the Weibull modulus, m. These parameters were determined by the linear regression method for K IC data measured at load of 9.81, 29.43, 49.01 and 98.1 N, respectively. It was found that the measured fracture toughness follow a Weibull distribution. © 2011 Inderscience Enterprises Ltd.
