The internal stress distribution of bagged fabric is studied theoretically and experimentally to investigate the influence of the stress distributions on fabric-residual-bagging deformation. A model is derived by using membrane theory to analyse the stress distributions for isotropic fabrics under different boundary conditions, including consideration of different bagging heights and the friction between the fabric sample and the steel ball deforming the fabric. The results indicate that a non-uniform distribution of meridian stress and a non-continuous distribution of hoop stress, along with bagging height, are important factors that may influence residual-bagging deformation and may cause localised damage of the fabric. To investigate the influence of fabric anisotropy on the bagging behaviour of a fabric, the stress distribution of an anisotropic fabric is studied on the basis of the measurements of tensile moduli in seven directions by using fabric strips and of the fabric strain calculated from the relation between the geometrical deformation and bagging height of a fabric. The analysis shows that a non-uniform stress distribution along the meridian direction and variation of the tensile angle θ may cause the difference in the yarn stresses between the warp and weft directions, resulting in different bagging shapes. Comparing predicted bagging forces with measured forces, it is found that the method is able to predict the trend of bagging force with some deviations. |
