External Stress
You can add the External Stress subnode to the Linear Elastic Material or Hyperelastic Material in order to specify an additional stress contribution which is not part of the constitutive relation. The external stress can be added to the total stress tensor, act as an extra load contribution, or behave as a residual stress.
In many cases External Stress and Initial Stress and Strain are interchangeable when prescribing stresses. In Initial Stress and Strain, the given stress is however always added to the stress tensor, whereas the option to use the stress as only a load contribution exists only in External Stress.
Shell Properties
Select the layer or layers for which this stress contribution is to be added.
When Use all layers is not selected.
If the external stress input type differs between layers, you will need to add several External Stress nodes with different layer selections.
If the same layer is selected in two External Stress nodes being active on the same boundary, the contributions will be added.
All other settings for the External Stress node are described in the documentation for External Stress in the Solid Mechanics interface.
