Dynamic Response of a Constrained Fibrous System Subjected to Transverse Impact. Part 1. Transient Responses and Breaking Energies of Nylon Yarns
Abstract
The effects of high-speed transverse missile impact upon textile yarns were observed by high-speed photography in a study of the transient behavior of a series of nylon 6/6 yarns differing systematically in mechanical properties. The loss in missile kinetic energy was determined directly from the reduction in missile velocity. The shape of these energy loss curves was due to the partition of missile energy into yarn kinetic energy and yarn strain energy. Estimates were made of the yarn breaking strains for these impact tests. The effects of yarn tenacity and impact velocity (strain rate) upon the impact behavior of these yarns were discussed and compared to their static behavior. Comparisons were also made with the effect of strain rate upon the breaking energies of nylon yarns reported in the literature.
