Topic: Form of shear strain for anisotropic OrthoLE
I need to use an OrthoLE material in the general anisotropic form where the 21 entries of the stiffness matrix are specified directly with a "stiff" entry. Does this material model expect values for for the strain components 4-6 (shear) as engineering strain (tau)? In other words, whould D66 for an isotropic material be E/2/(1+v) or E/(1+v)?
