| Resumo | |
Twisted continuous-filament yarn models for estimating breaking force and mechanical behavior rely on information such as yarn radius or surface angle twist, that are not readily available for a new yarn design. An easy-to-implement mechanical model for twisted continuous-filament yarns under pure tension is proposed, where the yarn geometry is generated by packing techniques and each filament individual mechanical behavior is calculated using traditional continuum mechanics/differential geometry formulation, leading to the progressive collapse of the yarn with the failure of each individual filament. Simulation results show good correlation with experiments for predicting breaking force in low-twist yarns, but diverging from the experimental curves at high twist values. (AU) | |
