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. Note that the time-integrated creep strain
εcr is computed for the sum of all creep rate contributions only; the same applies for the equivalent creep strain
εce.
The available settings in this section are the same as for the Creep node. The
Equivalent stress setting has an additional option —
From parent, which is default. When selected, the Additional Creep subnode will use the same equivalent stress
σe as in the parent Creep node.
