Abstract
Molecular dynamics simulations are used to investigate the effects of temperature and strain rate on the deformation of amorphous polyethylene. The simulations predict the effects of temperature and strain rate on the stress-strain responses, Youngs modulus and Poissons ratio similar to those observed in laboratory experiments performed by other researchers. The time-temperature superposition principle is applied to the Youngs modulus and Poissons ratio to form a master curve to address the discrepancies in strain rates between the simulations and the experiments. Differences in the numbers of monomers and chains, the degree of crystallinity and molecular orientation lead to discrepancies in the Youngs modulus and Poissons ratio between simulations and experiments.
