Polymers exhibit a rich variety of mechanical behaviour originating from their particular microstructure. To capture such intricate structure properties, a number of polymer constitutive models have been proposed and implemented into finite element codes in an effort to solve complex engineering problems. However, developing improved constitutive models for polymers that are physically-based has proven to be a challenging area with important implications for the design of polymeric structural components.
