Hello everyone!
I got this error in Abaqus/Explicit analysis: "Anisotropic and lamina elasticity is not allowed with a plasticity specification". It doesn't appear in Abaqus/Standard. It's really surprising, especially since I haven't found anything about it in the documentation. Shells must use the lamina definition for orthotropy so is it the case that it's not possible to define plasticity for shells with orthotopic elasticity in Explicit? Are there any workarounds other than switching to implicit dynamics (which is not reasonable in many cases)?
