A dynamic spring element model for the prediction of longitudinal failure of polymer composites
(2019-04)
Article
Open AccessA spring element model that takes into account the dynamic effects associated with fibre failure in composite materials is presented. The model is implemented in a parallel environment to allow a better performance in the ... -
A methodology to generate design allowables of composite laminates using machine learning
(2021-12)
Article
Open AccessThis work represents the first step towards the application of machine learning techniques in the prediction of statistical design allowables of composite laminates. Building on data generated analytically, four machine ... -
An analytical model to predict stress fields around broken fibres and their effect on the longitudinal failure of hybrid composites
(2019-03)
Article
Open AccessThis paper presents an analytical model to predict the stress redistribution around broken fibres in hybrid polymer composites. The model is used under the framework of a progressive failure approach to study the load ... -
Effective simulation of the mechanics of longitudinal tensile failure of unidirectional polymer composites
(Springer, 2017-12)
Article
Open AccessAn efficient computational model to simulate tensile failure of both hybrid and non-hybrid composite materials is proposed. This model is based on the spring element model, which is extended to a random 2D fibre packing. ... -
Effects of local stress fields around broken fibres on the longitudinal failure of composite materials
(2018-08-28)
Article
Open AccessAn in-depth analysis of the stress fields that surround a broken fibre in fibre reinforced composites is performed and the effects of different material properties are analysed. The stress fields obtained using a spring ...
