Mechanical behaviors such as elastic, thermoelastic, and viscoelastic textile composites involving multiple scales and complex geometries can be challenging to predict. Mechanics of structure genome (MSG) has been extended to accurately capture the above mechanical behaviors. Compared with traditional representative volume element (RVE) analysis using 3D finite element analysis (FEA), the MSG-based models provide same accuracy at a fraction of computing costs. Taking advantages of the advanced machine learning models such as neural network models, data-driven models have been developed to further accelerate the multiscale modeling of textile composites. The efficient surrogate models have been applied to model failure criteria of yarns, thermal conductivity, and failure strength of textile composites. The developed functions have been implemented into an open source code in the cloud called TexGen4SC, which is freely accessible and can be launched through a web browser (https://cdmhub.org/tools/texgen4sc) without installation.
