Polymer constitutive modelling: Formulation and computational aspects

Submitted by Mirkhalaf on
  • This work formulates an elasto-viscoplastic model at finite strains.
  • A particularly efficient numerical integration algorithm is presented.
  • A closed-form analytical expression is derived for the consistent tangent operator.
  • The non-linear behaviour of polymers is captured in the numerical examples.
  • Quadratic rate of convergence is successfully achieved.
