The Weibull modulus is expressed as the coefficient in the equation for a linear regression line when graphing ln (ln (1/ (1− P))) on the y -axis against ln (X − Xu) on the x -axis. In the field of materials science, the shape parameter k of a distribution of strengths is known as the Weibull modulus. In the context of diffusion of innovations, the Weibull distribution is a "pure" imitation/rejection model.

The Weibull modulus was determined by a series of strength data, which were calculated by the simulated bending tests of the samples. The number density of coarser defects was given by the assumed power function. The various Weibull moduli were obtained for some kinds of series.

Sets with low Weibull modulus have a more broad range of failures. Em probabilidade e estatística a distribuição de Weibull é uma distribuição de probabilidade contínua.

Em probabilidade e estatística a distribuição de Weibull é uma distribuição de probabilidade contínua. É nomeada devido a Waloddi Weibull que em 1951 lançou um artigo descrevendo a distribuição em detalhes e propondo diversas aplicações [1].

The main tendency of size effect in brittle materials is that a more brittle material commonly produces a lower value of m. Accuracy of the LS methods for Weibull modulus and characteristic strength essentially depend on plotting position and sample size. Large sample sizes (n≥30) support a credible Weibull parameters estimation. An important complement of the point estimates of Weibull parameters is provided by the Menon 95%CI. There are several approaches to the estimation of the Weibull modulus in Eq. [ 2 ], with the most common methods being the Linear Least Squares method (LLS) and the Maximum Likelihood method (ML). Many researches focused on the bias of the estimated Weibull modulus obtained by the estimation methods.
