Linear Viscoelastic Predictions Using a Single-Chain Mean-field Discrete Slip-link Model

摘要

Currently, there is substantial interest in predicting linear viscoelasticity data through the use of computational modeling. Tube models have been long used for this calculation, but limitations with the model have spurred research in different computational techniques. One such theory is the self-consistent single chain mean-field discrete slip-link model developed by Schieber and coworkers. This theory has been programmed by Schieber and coworkers into a FORTRAN90 code, and has been made available to the U.S. Army Research Laboratory. In this report, we give an overview of the theory, as well as an introduction on how to use this program. We use this program to calculate the storage and loss modulus for polystyrene. This data is compared to experimental results.
