The Layered Linear Elastic Material node adds the equations for a layered linear elastic membrane.
By adding the following subnodes to the Layered Linear Elastic Material node you can incorporate many other effects:
For this node, the Shell Properties section is only used for selecting a material model, but not individual layers.
The boundary selection in this node is similar to the Linear Elastic Material node. It is however only possible to select boundaries which are part of the selection of a layered material defined in
Layered Material Link or
Layered Material Stack node.
Select a linear elastic Solid model —
Isotropic,
Orthotropic, or
Anisotropic and enter the settings as described for the
Linear Elastic Material for the Solid Mechanics interface. If the layers have different types of anisotropy properties, select the one that is most complex.
Select the Calculate dissipated energy check box as needed to compute the energy dissipated by
Creep,
Plasticity,
Viscoplasticity or
Viscoelasticity.
If Pressure formulation is used, select the discretization for the
Auxiliary pressure —
Automatic,
Discontinuous Lagrange,
Continuous,
Linear or
Constant. If
Strain formulation is used, select the discretization for the
Auxiliary volumetric strain —
Automatic,
Discontinuous Lagrange,
Continuous,
Linear or
Constant.
Select the Reduced integration check box to reduce the integration points for the weak contribution of the feature. Select a method for
Hourglass stabilization —
Automatic,
Manual, or
None to use in combination with the reduced integration scheme. The default
Automatic stabilization technique is based on the shape function and shape order of the displacement field.
When Shear stabilization is selected, enter a stabilization shear modulus,
Gstb, and the shear correction factor
kstb. The value for
Gstb should be in the order of magnitude of the equivalent shear modulus.
When Volumetric stabilization is selected, enter a stabilization bulk modulus,
Kstb. The value should be in the order of magnitude of the equivalent bulk modulus.
