dc.description.abstractThe objective of this research is to study of the changes in energy during the cyclic deformation of woven fabrics. An experimental study was undertaken to investigate the energy changes in the fabrics during tensile cyclic loading. The hysteresis was used to study these changes in the fabrics during cyclic loading conditions. The experiments were divided into two parts. Three directions of loading were tested for this experiment, which is the warp, the weft and the diagonal directions. In the first part, the strength and breaking elongation of the fabric samples were measured in these directions. The results of which were used to develop the cyclic deformation parameters. The cyclic deformation tests were done at 20% and 50% of the length of breaking elongation. This study found that the direction of load has a major impact in the change in energy in the fabric. The hysteresis is higher in the diagonal direction as compared to the two principal directions. The hysteresis is higher at increased length of the cycle and higher at a slower loading speed. With the research objective in mind, the hysteresis results gave an indication of how the energy changes in the woven fabric during cyclic deformation.cs
