A Model of Rigid Bodies for Plain-Weave Fabrics Based on the Dynamics of Multibody Systems

Woven structures form the fundamental difference between woven fabrics and general continuum medium materials. This paper proposes a fabric modeling technique giving a realistic cloth simulation based on the description of woven structures. The 'three-element unit cell' of woven structure is put forward to describe the inherent connectivity between yarns. Applying the dynamics of multibody systems theory, a model of rigid bodies for plain-weave fabrics (MRBF) is presented. For uniaxial tensile, qualitative and quantitative dynamic analyzes are carried out. Our qualitative analysis reveals the strong coupling interaction between yarns and the mechanism of crimp interchange. The model is validated by comparison of our simulation results with qualitative analysis and with those obtained from Kawabata Evaluation System for Fabrics (KES) uniaxial tensile experiment.
