The proposed material model consists of a three nonlinear elements to model the yarns, and an isotropic plate to model the coating.
The longitudinal compression and transverse expansion were integrated in a mechanical model of the yarn.
The curve model representing the yarn is generated from the stitch mesh, then the final shape is computed by a yarn-level physical simulation that locally relaxes the yarn into realistic shape while preserving global shape of the garment and avoiding "yarn pull-through," thereby producing valid yarn geometry suitable for dynamic simulation.
His hair, never cut, falls to the middle of his back in gentle waves, exactly the hair I remember the new corn silk Cabbage Patch kid dolls having when I was a kid, when I begged and pleaded with my mother to get me one and instead she bought me the older model with the yarn hair.
The approach relies on the selection of a geometric model for the fabric weave, coupled with constitutive models for the yarn behaviors.
The paper therefore presents the creation of a, as realistic as possible, 3D geometrical model of the yarns of complex unit cells.
The aim is to capture the essence of the response of a unit cell in a single representative shell element, which would replace the more complicated and numerically costly 3D solid model of the yarns in a crossover.
Most of the work is focused on modelling the fibre-yarn relationship, yarn tenacity, fault detection, compression, elastic properties and hand values of woven, nonwoven and knitted fabrics.
In order to handle the associated high level of complexity, we propose a new GFEM-like approach for modeling the CMC yarn, which is considered to be an appropriate modeling scale.
The meso-scale model is developed using the finite element method, with the yarn modelled as a continuum.
