Strain Hardening of Polymer Glasses : Effect of Entanglement Density , Temperature , and Rate

Abstract

The strain hardening behavior of model polymer glasses is studied with simulations over a wide range of entanglement densities, temperatures, strain rates, and chain lengths. Entangled polymers deform affinely at scales larger than the entanglement length as assumed in entropic network models of strain hardening.The dependence of strain hardening on strain… (More)
