Constitutive modeling of the finite strain behavior of amorphous polymers in and above the glass transition
Rebecca B. Dupaix,Mary C. Boyce +1 more
TL;DR: In this paper, a constitutive model is developed to capture the rate-dependent stress-strain behavior of an amorphous polymer (poly(ethylene terephthalate)-glycol (PETG)) at temperatures in and above the glass transition (θg).

A Model Treating Tensile Deformation of Semicrystalline Polymers: Quasi-Static Stress−Strain Relationship and Viscous Stress Determined for a Sample of Polyethylene
TL;DR: In this article, a model for tensile deformation of poly(ethylene-co-12% vinyl acetate) (PEVA12) was proposed, which treated the stress as arising from quasi-static stresses originating from the stretched network of entangled chains in the fluid regions and from the force-transmitting skeleton of crystallites, plus the viscous forces described by Eyring's equation.

Modeling of deformation behavior and strain-induced crystallization in poly(ethylene terephthalate) above the glass transition temperature
TL;DR: In this article, a constitutive model for large deformation stress-strain behavior and strain-induced crystallization in poly(ethylene terephthalate), at temperatures above the glass transition temperature, is proposed.
Journal ArticleDOI
A study of strain-induced crystallization of polymers
TL;DR: Rajagopal et al. as mentioned in this paper used a recent framework that associates different natural states and material symmetries with distinct microstructures of the body and studied the problem of strain-induced crystallization of polymeric materials.

The effect of entanglements in rubber elasticity
Sam F. Edwards,T. A. Vilgis +1 more
TL;DR: A theory of rubber elasticity based on the concept of entanglements was presented in this paper, where it was shown that for small deformation the molecular mechanism of stretching is dominated by the slippage of chains.

A constitutive model for the nonlinear viscoelastic viscoplastic behavior of glassy polymers
O. A. Hasan,Mary C. Boyce +1 more
TL;DR: In this article, the authors modeled the nonlinear viscoelastic behavior as an elastic-inelastic transition, where the energetically distributed nature of inelastic events and their evolution with straining was taken into account.

Glass-rubber constitutive model for amorphous polymers near the glass transition
C.P. Buckley,D.C. Jones +1 more
TL;DR: In this article, a physically based, three-dimensional constitutive model was developed for simulating this wide range of features in models of polymer products and processes, and is therefore an example of a glass-rubber constitutive approach.
