Prediction of Tensile Behaviour of Laterally Crushed Filaments Using Finite Element Method

Abstract

Nylon monofilament and polyester multifilament yarn find applications in fishing nets and parachute fabrics , each of which might demand different load levels to be sustained without breaking. While usage, it is quite likely that few places/spots in the yarn may get permanently deformed due to the application of high transverse compressive stresses. Such "Weak spots" in yarn are amenable to breaks. The aspect of lateral or transverse compression was studied with a crushing instrument that applied forces laterally on the filaments. The tensile properties of such filaments were obtained experimentally and were simulated using FEM. A good correlation was seen between theoretical as well as experimental values.
