Constitutive modeling for time and temperaturedependent behavior of composites
08 Jan 2020  Contributor(s):: Orzuri Rique, Xin Liu, Wenbin Yu, Byron Pipes
Structural integrity, durability, and thermal stability represent critical areas for adequately modeling the behavior of composite materials. Polymeric matrices are prone to have timedependent behavior very sensitive to changes in temperature that influence the effective properties of the...

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...
