Validation of a new numerical weaving tool highlighting the influence of real yarn positions and shapes on their behaviour under impact

Abstract : In this study, a numerical simulation approach is used to measure the influence of yarn positions inside a 3D warp interlock fabric submitted to impact. Four numerical results have been compared to one experimental impact test. A first simulation is made directly from the experimental tomographic view of the woven fabric to agree with the real positions and sections of threads. A second simulation is made with an ideal finite element (FE) model of the 3D woven architecture obtained by our automatic tool Ktex-Pattern©™. In order to improve the volume rate of fibers, two other calculations are made by a modification of the woven structure. The maximal displacement and the characteristic duration of the ball penetration enable us to compare the simulations and experiments. Additionally, we focus on a genuine method to generate automatically the most realistic and reliable FE model of a weave diagram.
