Finite element simulation of ballistic impact on single jersey knit fabric

Mechanical behaviour of 3D monofilament knitted fabrics: Modeling, simulation and validation

“…At 22% strain, significant geometrical changes have occurred to the structure-based element; this phase has been highlighted by several authors. 26,27 At the beginning of the stretching mode, structures (a) and (c) have undergone a significant form change with the overlapping of nodes, which might cause numerical convergence issues. Unlike tie structures, which endure width restriction and length elongation without causing out-of-plane rotation, the mechanical reaction is mostly controlled by the stiffness of the yarn in this strain range.…”

“…The design geometry technique was used to represent each part of the stitch similar to. 26 The relaxation of the yarns from residual stresses is accompanied by the decrease of existing deformations generated by the knitting process. The yarns slide over each other during relaxation until the minimal elastic energy structure, on which we build our geometrical model, is reached.…”

Yarn-Level Modeling of Non-Uniform Knitted Fabric for Digital Analysis of Textile Characteristics - From a bitmap to the yarn-level model

“…The design force models reproduce macroscopic characteristics of knitted fabrics. McKee et al, 2017 andLiu et al, 2018 use finite element analysis to check the behavior of textiles on a yarn-level scale. Sperl et al ( 2020) have proposed a method of animating yarnlevel cloth effects using a thin-shell solver.…”

Prediction of mechanical properties of knitted fabrics under tensile and shear loading: Mesoscale analysis using representative unit cells and its validation

“…The main reason is that woven fabrics are made by interlacing slightly crimped fibers orthogonally. As a consequence, they possess very 105 little stretchability [15]. On the other hand, knitted fabrics are produced by looping the yarn through itself to make a chain of stitches that are subsequently connected together.…”

“…Furthermore, based on that model Abghary et al [10] have proposed a novel geometrical model for 1 × 1 rib knitted fabrics. Recently, McKee et al [15] have utilized trigonometric functions to describe the heart line of the knitted yarn. The parameters in that model were calibrated with X-ray tomographic images.…”
