External Strain
The External Strain subnode allows you to provide inelastic strain contributions to the Linear Elastic Material on a variety of formats.
Layer Selection
Select the layer or layers for which this strain contribution is to be added. The Layer selector inherits the value set in the parent Linear Elastic Material node. When it is set to All layered materials, you cannot access the individual layers.
If the same layer is selected in two External Strain nodes being active on the same boundary, the contributions will be added.
•
All other settings for the External Strain node are described in the documentation for External Strain in the Solid Mechanics interface.
•
For a general description of layer and interface selections, see The Layer Selection Section.
•
You can describe strain values with a through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
