Modeling of Clothing
- Modeling of very flexible systems (clothing) as shells and membranes at arbitrarily large deformations;
- Contact modeling between clothing and the human, and self-contact between portions of the same garment;
- Developing suitable constitutive models that account for the fibers comprising the fabric, and their evolving woven or knitted structure in the garment;
The third issue is especially challenging since the yarns slide (irreversibly) relative to one another under deformation of the fabric, and this needs to be captured in fabric constitutive models, since it impacts the incremental stiffness response of the fabric (Fig. 1).
