Initial failure strength prediction of woven composites using a new yarn failure criterion constructed by deep learning
05 Jun 2019 | Publications | Contributor(s): Xin Liu, Federico Gasco, Johnathan Goodsell, Wenbin Yu
A new failure criterion for fiber tows (i.e. yarns) is developed based on a micromechanical model using mechanics of structure genome (MSG) and deep learning neural network. The proposed failure criterion can be applied to yarns in mesoscale textile composites modeling while capturing the failure...
