Use the Additional Creep subnode to define additional contributions to the creep model defined by the parent
Creep node, such as primary or tertiary creep behavior. A
Creep node can have any number of
Additional Creep subnodes with different settings to model advanced creep mechanisms.
When the creep model differs between layers, you will need to add several Additional Creep nodes with different layer selections. If the model is the same, and only the material data values differ, you can use a single
Additional Creep 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 Creep nodes being active on the boundary, then there will be two creep strain contributions.
