Until now, the pin-jointed net model has been a widely used method for the prediction of preforming shape for woven fabrics. However, it deals only with pure trellising (or shear) and neglects other possible deformation modes. In some cases, there is evidence showing that other deformation modes have relevance to, and effectiveness in forming the final shape. A model considering only the shear mode will not result in an adequate prediction. In this study, a slippage model is developed to modify the pin-jointed net model. Macrostructure of the fabrics is included in the slippage model in order to capture more deformation modes. Comparisons of experimental and simulation results are presented. It is shown that the numerical prediction using the slippage model has better agreement with experimental measurements.
