Initial failure strength prediction of woven composites using a new yarn failure criterion constructed by deep learning
0.0 out of 5 stars
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...
Generalized Free-Edge Stress Analysis Using Mechanics of Structure Genome
22 Aug 2016 | Publications | Contributor(s): Bo Peng, Johnathan Goodsell, Byron Pipes, Wenbin Yu
This work reveals the potential of mechanics of structure genome (MSG) for the free-edge stress analysis of composite laminates. First, the cross-sectional analysis specialized from MSG is formulated for solving a generalized free-edge problem of composite laminates. Then, MSG and the companion...
