Plasticity

Use the subnode to define the properties for modeling elastoplastic materials. This material model can be used together with either a Linear Elastic Material, Nonlinear Elastic Material, or a Layered Linear Elastic Material and requires the Nonlinear Structural Material Module.


	See also the discussion in Layered and Nonlayered Membranes.

Table 7-3: Layer Selections; Plasticity
Selection	Use All Layers	Selection of Individual Layers
Boundary	Same as parent selection when the node is added.	When Use all layers is not selected. Only a subset of the layers selected in the parent can be selected.

If the plasticity model differs between layers, you will need to add several nodes with different layer selections. If the model is the same, and only the material data values differ, you can use a single node where is used to define the values. The data for each layer is then received from global nodes.

If there are two nodes where the same layer is selected on the same boundary, the latter will be overridden on the common selections.

All other settings for the node are described in the documentation for Plasticity in the Solid Mechanics interface.
