- Universal mechanical modeling of fiber bundle under torsion: An experimental and numerical study Chi Zhang Hongbo Hu Yang Liu Kunkun Zhu Liquan Jiang Hao Yu Weilin Xu Polymer Composites AbstractIn this paper, a universal mechanical model for the torsional behavior of fiber bundle was established, grounded in the principles of spatial geometry and continuum mechanics, incorporating differential geometry formulas. The model was validated through self‐designed experimental equipment and finite element simulations using Ansys Workbench, showing strong agreement between predicted torsional fracture behavior and experimental results. The study further examined the contributions of fiber bending, torsion, and tension to the overall torque, revealing that torsion plays the dominant role. Additionally, the effect of filament count on the torsional performance of fiber bundles was analyzed, demonstrating that while the number of fibers significantly influences stress distribution, its impact on overall torque is minimal.Highlights A universal mechanical model for fiber bundle torsional is proposed. High consistency between simulation and experimental results. Examined filament count effect on torsional strength. More filaments reduce stress concentration, improving performance. 10.1002/pc.29092 http://onlinelibrary.wiley.com/termsAndConditions#vor
