"WebFrom the perspective of weakest link theory, the conventional Weibull scaling law given in Equation (5) emerges as a consequence of the fact that a larger specimen contains more ﬂaws than a smaller one and therefore has a higher probability for its weakest ﬂaw, i.e., the largest due to LEFM, to be weaker than the one in the smaller.

We show that in contrast with the Weibull and the modified gamma, the hazard function of the κ-Weibull is non-extensive, which is a signature of inter …

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.
