Modeling Linear Viscoelasticity in Glassy Polymers using Standard Rheological Models
Veröffentlicht in 2011
In this study, a capability has been developed for modeling the linear viscoelastic behaviour of a glassy polymer using COMSOL Multiphysics®. The two rheological models by Maxwell and Kelvin-Voigt were used for modeling stress relaxation and creep loading behavior, respectively, of a typical gas pipe under two modes of plane stress and plane strain.
An advantage of the developed model is its ability to predict either the modulus or compliance of a glassy polymer when only one set of experimental data is available. This is readily achieved by conducting a 2D analysis using one of the two rheological models which corresponds to the available experimental data.
