chrono::fea::ChElasticityReissnerIsothropic Class Reference
Description
Elasticity of 6-field Reissner-Mindlin shells (kinematically-exact shell theory as in Witkowski et al.) to be used in a ChMaterialShellReissner.
This class implements material properties for a layer from the Reissner theory, for the case of isotropic linear linear elastic material. This is probably the material that you need most often when using 6-field shells. Previously: ChMaterialShellReissnerIsothropic
