History
The PolymerFEM web site was created by Dr. Jorgen Bergstrom in March 2002.
Background
This site is an independent forum for discussing constitutive models for polymers and their implementation in general purpose finite element programs. What you will find here are general information about material behavior, useful constitutive models, and numerical implementations. The goal of this site is to become a useful reference for constitutive models for polymers. Researchers and users are encouraged to submit results and to request information.
Shift Functions and Reduced Time
Hi, .
shriisall 2010-09-07 14:31For thermorehelogically simple materials in viscoelasticity, we know that the use of shift functions to calculate relaxation times (tau) at different temperatures
tau(T) = tau(Tref)A(T) ...
