  1. 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...

  2. MSC.Patran/Nastran-SwiftComp GUI

    01 Apr 2019 | Contributor(s):: Xin Liu, Wenbin Yu

    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...

  3. Predict elastic properties of plain woven composites

    Problem Description The MSG solid model is used to predict the effective properties of a plain weave composite using a two-step approach. This problem is the first example in the paper “Liu,...

  4. Predict failure index, strength ratio, and failure envelope of 3D orthogonal woven plate

    Problem Description In this example, failure index, strength ratio, and failure envelope of a 3D orthogonal woven plate are predicted using MSG failure functions. For computing failure index and...

  5. Predict initial failure strength constants of plain woven composites

    Problem Description Predicting the failure initiation is the first step for many failure analyses of composites. A popular approach is the multiscale failure analysis, which computes the...

  6. TexGen4SC Tutorial #1: Homogenization Analysis of Textile Composites with Arbitrary Inter-ply Shifts

    03 Jan 2017 | Contributor(s):: Xin Liu, Wenbin Yu

    This tutorial shows how to use TexGen4SC to perform homogenization analysis of textile composites with arbitrary inter-ply shifts. A companion video is available on YouTube. TexGen4SC can be launched directly from https://cdmhub.org/tools/texgen4sc. A python script for the...

  7. 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...
