Abstract
This article proposes a near micro-scale modelling technique to predict nonlinear shear behaviour of dry woven fabrics in a picture frame test using the digital element method. In the proposed model, the fabric yarns are modelled as bundles of virtual fibres that are then modelled by the truss elements in finite element code. Additionally, our finite element analysis was performed in a repeated unit cell and the contact friction among the fibres is explicitly considered. Especially, we proposed so-called enhanced periodic boundary conditions to capture the mechanical behaviour of fabrics both in the small and large shear angle regimes.
Keywords: PERIODIC BOUNDARY CONDITIONS, FABRIC SHEAR HOMOGENIZATION
