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 graphical user interface (GUI) has been developed to integrate SwiftComp into MSC.Patran/Nastran for constitutive modeling and providing the automated conversion of the MSG plate and beam stiffness matrix into MSC.Nastran shell and beam element properties and materials. In order to reduce...
Two-step homogenization of textile composites using mechanics of structure genome
04 Apr 2017 | Contributor(s):: Xin Liu, Khizar Rouf, Bo Peng, Wenbin Yu
Mechanics of structure genome is extended to provide a novel two-step homogenization approach to predicting the effective properties of textile composites. The first homogenization step (microhomogenization) deals with determining the effective properties of tows (yarns) from fiber and matrix...
