Abstract
An analytical and non-linear finite element (FE) modelling approach of plain weave fabric reinforcements have been developed to predict shear force for pure shear condition. For simplicity two main components of force for shear deformation has been considered; one is force required for the elastic deformation and another is to overcome the frictional resistance. Coulomb friction model of ANSYS is used in the FE model whereas the boundary condition has been established using Lagrangian description. Modelling of frictional resistance due to contact between yarns and crossover are conducted by utilizing contact pair option in ANSYS. A good agreement between theoretical and FEA model have been obtained. To ensure pure shear deformation in the fabrics it has been proved that there are no stress (von Mises and normal) or tension exist in the deformed yarn.
