The present study focuses on the experimental and simulation analysis of the tensile fracture behavior of twisted yarns. A quasi-fiber scale model of twisted yarns made of HMWPE fibers is established using virtual fibers. The tensile fracture behavior of twisted yarns is simulated using a maximum stress criterion with a random distribution of properties. The tensile fracture loads of six kinds of twisted yarns agree well with the experimental results. The numerical precision and dispersion of the proposed method are analyzed systematically. The influence of damage factor and displacement at failures on the simulation results of twisted yarns are also obtained. Above modeling and analysis method provides a helpful tool for understanding the yarn architectures of fiber reinforced composites.enDla wszystkich w zakresie dozwolonego użytkuFair use conditiontensile fracture behaviortwisted yarnvirtual fiberquasi-fiber scalenumerical simulationzachowanie przy pękaniu na rozciąganieprzędza skręcanawłókno wirtualneskala quasi-włóknowasymulacja numerycznaartykuł - konferencjaLicencja PŁLUT License10.34658/9788366741751.19
