Knitted fabrics are hierarchically structured materials exhibiting a complex set of structure-property-behavior relations driven by yarn-level interactions. While manufacturing capability is sufficiently advanced to allow digital design and production of elaborate three-dimensional knit structures from a diverse array of materials, a lack of predictive simulation capability hinders progress in deployment of functional fabrics, which are envisioned as tailorable platforms for applications such as actuation or medical sensing. A key objective of this work is to develop robust, efficient data-driven simulation tools to study mechanical/multi-physics behavior of smart textiles. To this aim, we implement an ICME strategy linking mechanical testing, numerical simulation, computational mechanics, and manufacturing. Effects of geometrical variation on the mechanical response of several common knit structures are parametrically investigated using Finite Element Analysis. Furthermore, reduced-order representations of knitted fabrics are generated and compared with direct numerical simulations (DNS) and mechanical tests on their manufactured counterparts.
