Simulation of Stress–Strain Curves of Polyester and Viscose Filaments

Abstract

Eyring’s non-linear visco-elastic model has been used to simulate stress–strain behaviours of polyester and viscose filaments. The complex mathematical equations of Eyring’s model for curve fitting are handled by non-traditional optimization methods such as genetic algorithm. The findings show that Eyring’s model can be used to simulate the stress–strain behaviours of the polyester and viscose filaments with reasonable degree of accuracy. It can also decipher the underlying molecular mechanism of the stress–strain behaviours.
