WebThe Weibull statistical fracture theory is widely applied to the fracture of ceramic materials. The foundations of the Weibull theory for brittle fracture are reviewed. This theory … Webstatistical theory. One of the first attempts in this direction was made by Weibull [1]. Based on weakest-link theory he stated the probability distribution which bears his name. The basic premise for the model is that all materials contain inhomogeneities which are distributed at random with a certain density per unit volume.
