I am trying to create 3d orthotropic material for composite solid elements.First question C23 semms right in patran interface when i look into stiffness matrix but C23 changes in exported bdf. My second question is Nastran takes C44=G12, C55=G23 and C66=G31 but in composite material books it is given C44=G23, C55=G31 and C66=G12. Can someone explain what i miss?

Thanks in advance. Have a nice day.
