"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.
