摘要：

In this work, we explore the application of the novel technique Sound Measurements (SM) on E-glass fibre bundles. This technique relies on the ability to capture the sound emitted when fibres break. The method was used to monitor the failure of fibres and to generate a set of effective values of strength for the glass fibres within a bundle. The numerical experiments showed that not only did this methodology provides a more accurate representation of the features observed in the mechanical test, but also a better coefficient of determination R-2 in relation to the Weibull analysis.
