Numerical Simulation of Semi-blunt Puncture Behaviors of Woven Fabrics Based on the Finite Element Method

This paper focuses on the semi-blunt puncture behavior of woven fabrics via finite element analysis (FEA) approaches. In these finite element (FE) models, main structure parameters, such as weave structure, warp density as well as friction coefficient, are systematically considered and calculated via FEA. These microstructure geometrical models are builtup with full consideration of interaction between warp and weft yarns. The theoretical results show that plain woven fabric has better puncture resistance compared with 2/1 twill and 5-harness satin fabrics. With the increase of warp density and friction coefficient, the puncture property of woven fabric will be dramatically improved. Finally, an energy consumption method is adopted to analyze the puncture damage process of woven fabric. The simulation results will benefit for the optimum design of woven fabric with excellent puncture performance.
