Abstract
In a previous paper, the computer aided design (CAD)/computer aided engineering (CAE) approach was presented and compared via the stress–strain curves of high-tenacity rayon yarn and the energy method. The maximum stress–extension curves showed very good agreement with experimental results and were more accurate than the previous methods. In this paper, the CAD/CAE method is considered in relation to multifilament yarn, which is equally applicable to a wide range of man-made filament yarns from nine material types. The results of this prediction model were compared with the stress–strain curves of experimental results and the energy method. The maximum stress–extension curves showed very good agreement with the experimental results except for the high-tenacity Terylene and Fortisan. The reasons for the poor agreement between the experimental and predicted curves are discussed. The breaking points obtained with this method are also compared with experimental results and discussed.
