Additional Network
Use the Additional Network subnode to define additional contributions to the Parallel Network model defined by the parent Polymer Viscoplasticity node. A Polymer Viscoplasticity node can have any number of Additional Network subnodes with different settings to model advanced viscoplastic mechanisms.
The Nonlinear Structural Materials Module is required for this feature. For details, see www.comsol.com/products/specifications/.
Shell Properties
Select the layer or layers for which this creep model is to be used.
When Use all layers is not selected.
When the Parallel Network model differs between layers, you will need to add several Additional Networks nodes with different layer selections. If the model is the same, and only the material data values differ, you can use a single Additional Network node where From material is used to define the values. The data for each layer is then received from global Layered Material nodes.
If the same layer is selected in two Additional Network nodes being active on the boundary, then there will be two additional contributions
