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. WebThe Weibull modulus is a shape parameter for the Weibull distributionmodel which, in this case, maps the probability of failure of a component at varying stresses.

WebFiber strength statistics is found to have an effect on composite mechanical properties, and the use of the power-law model is relatively efficient for modeling purposes in comparison to the linear- law model, which could be attributed to fiber diameter variation. In fibrous composites, tensile strength of reinforcements exhibits a stochastic nature, and the … WebWe investigate two new distributions that exhibit weakest-link scaling, i.e., a Weibull generalization known as the κ-Weibull and a modified gamma probability function that we propose herein. 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 …
