Initial failure strength prediction of woven composites using a new yarn failure criterion constructed by deep learning

05 Jun 2019 | 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...

A Unified Approach for Thermoelastic Constitutive Modeling of Composite Structures

07 Feb 2019 | Contributor(s): Xin Liu, Wenbin Yu, Federico Gasco, Johnathan Goodsell

Mechanics of structure genome (MSG) has been extended to provide a unified approach to predict the thermoelastic behaviors of composite structures. The variational statement of the MSG models has been modified to capture pointwise temperature distribution in composite structures. The effective...
