The Linear Elastic Material node adds the equations for a linear elastic shell and an interface for defining the elastic material properties.
By adding the following subnodes to the Linear Elastic Material node you can incorporate many other effects:
A Shell Local System subnode is always added. In this node you specify the coordinate system in which material orientations and results are interpreted. You can add several
Shell Local System nodes in order to control the local directions on different boundaries.
Select Material symmetry—
Isotropic,
Orthotropic, or
Anisotropic and enter the settings as described for the
Linear Elastic Material for the Solid Mechanics interface. Note that:
If the Solve for out-of-plane strain components check box is selected, extra degrees of freedom will be added for computing the out-of-plane strain components. This formulation is similar to what is used for plane stress in the Solid Mechanics and Membrane interfaces, and it is computationally somewhat more expensive than the standard formulation. In the default formulation, the out-of-plane strain in the shell is explicitly computed from the stress. This may cause circular references of variables if you for example want the constitutive law to be strain-dependent. If you encounter such problems, use the alternative formulation.
If a study step is geometrically nonlinear, the default behavior is to use a large strain formulation in all domains. Select the Geometrically linear formulation check box to always use a small strain formulation, irrespective of the setting in the study step.
