The Mechanical Properties of Woven Fabrics

Deformation mechanism of the elastic region which follows the nonlinear frictional region in shearing of plain-weave fabrics is analyzed, and the elastic shear modulus is determined in terms of the mechanical properties of the yarn and the geometrical parameters of the fabric. The mechanical behavior of the three-dimensional unit cell of plain-weave fabrics is studied, based on a simple model of yarn in relative slipping of yarns at the intersection of the fabric. The effect of tension being applied in shear tests is also included in the analysis. The elastic shear modulus determined by the proposed mechanism of deformation is found to agree well with experimental results.
