An iterative method to obtain the specimen-independent three-parameter Weibull distribution of strength from bending tests
Abstract Brittle materials, such as glass and ceramics, usually present a large strength scatter. Among other probability distributions, the Weibull distribution is widely used to characterize their resistance. Often the two-parameter model is...
