Hypersizer can define two types of laminate:
Effective Laminate (EL)
Discrete Laminate (DL)
When exporting a Hypersizer database to a FEM the user must be aware of the limitations:
Effective Laminate (EL) – Effective laminates are defined in terms of %age of plies in direction 0°, 90°, +45°,-45°. MAT2 smeared properties are created when exporting to a FEM. We can not export a EL to a MAT8 and PCOMP because the laminate definition does not have sufficient information to fully describe a laminate and create a PCOMP for Nastran.
The Nastran export options are selected in the Project Setup Form. Ensure the correct export options are selected.
Discrete Laminates (DL) – A discrete laminate is a ply stacking sequence and fiber orientation. MAT8 and PCOMP properties are created when exported a DL to a FEM. A DL is defined in the LAMINATE form or HyperLAMINATE form.
