1. The OHC and OHT calculations do not appear in the Laminate Analysis form. In addition, laminate based failure modes are also not available from this form. The laminate analysis form only uses ply based failure modes.
2 In the sizing form, the laminate based allowables are based on percentage of plies in each direction. Because the curves that contain these allowables are generally based on tests on non-hybrid laminates (all plies of the same materials), the % of plies in each direction for a hybrid laminate loses its meaning.
When we implemented the laminate based failure method, it was decided that laminate based analysis would not be performed on hybrid laminates. I believe that is what is causing the "N/A Material" message on the failure tab.
