Abstract
Textile materials with negative Poisson′s ratio possessed auxetic behavior and excellent properties which resulted in all kinds of potential applications in various fields. This paper aims to study the deformation behavior and auxetic mechanism of complex yarns with negative Poisson′s ratio by the finite element software Abaqus. The analysis results showed as Poisson′s ratio under certain axial strain were corresponding to the experimental results that have been reported. Then the deformation process and reason were discussed according to the Mises Stress distributions. The differences between auxetic yarns with elastic and hyperelastic core were also compared and analysed from Poisson’s ratio, load and normal contact pressure. The finite element modal and analysis was expected to be a positive guidance to prepare auxetic yarns with obvious auxetic effect.
