Model Theory

The Parallel Network (PN) model is an advanced material model for predicting the non-linear viscoplastic response of any polymer material. The rheological structure of the model can be represented using a number of parallel networks, as shown in the following figure.



The PN model is a generalization of both the Bergstrom-Boyce (BB) model, and the Three Network (TN) model. Depending on the selected model structure, the material model can predict almost any isotropic or anisotropic response.


Supported Model Components The following is a summary of the different supported components and models that can be used with the Parallel Network (PN) model. The details of these different model options are presented in the PolyUMod User's Guide. The model supports the following elastic c...
