What is the meaning of smear in PCOMP card, to define orthotrophic material lay-ups? In which situation, this smear option is used? When I see the Nastran help, it says ply effects are smeared and the stacking sequence are ignored. If stacking sequnce are ignored, how the analysis will be right...
I primarly used hypermesh (pre-post), optistruct (linear solver and optimizer) and LSdyna (explicit) in automotive industry. Now we have some aerospace products to be analysed. I was impressed by fellow members in this forum about the capability of NEiNastran for the price. As we already have...
I am doing simple buckling analysis on a carbon fiber tublar product subject to compressive load. I use NE nastran. My model contain PCOMP card and MAT8 card. I have the material property for the carbon prepreg from the supplier from which I am pluging in all the values in MAT8 card. In MAT8...
