Use the Hygroscopic Swelling subnode to add an internal thermal strain caused by changes in temperature.
Hygroscopic swelling can be added to Linear Elastic Material,
Linear Elastic Material, Layered,
Nonlinear Elastic Material, and
Hyperelastic Material. For
Linear Elastic Material, Layered, swelling can be applied to arbitrary layers in a multilayered membrane when the Composite Materials Module is available.
If the Moisture concentration type differs between layers, you will need to add several
Hygroscopic Swelling nodes with different layer selections. If only the material data values differ, you can use a single
Hygroscopic Swelling node with
From material. The data for each layer is then received from global
Layered Material nodes.
If the same layer is selected in two Hygroscopic Swelling nodes being active on the same boundary, the second definition will override the previous.
