Description
Isothropic elasticity for thin shells (Kirchoff-Love shell theory, without shear effects) to be used in a ChMaterialShellKirchhoff.
This class implements material properties for a layer of a Kirchhoff thin shell, for the case of isotropic linear elastic material. This is probably the material that you need most often when using thin shells.
