Yarn Pull-Out as a Mechanism for Dissipating Ballistic Impact Energy in Kevlar~(~R) KM-2 Fabric Part Ⅱ: Predicting Ballistic Performance

摘要

The energy absorbed in ballistic fabrics is modeled by assuming yarn pull-out, including yarn uncrimping and translation, as the primary energy absorption mechanism. Using a semi-empirical model of yarn pull-out based on laboratory tests, predictions of fabric ballistic performance are compared to ballistic test results. The study demonstrates that quasi-static pull-out results can be correlated quantitatively with yarn pull-out during ballistic impact.
