This is a 2 DOF pitch plunge theoretical model of flutter. You can use an internet search to find university lectures deriving the EOM. Nastran is overkill unless you have specific wing geometry, materials, and input functions predefined.
So I am still uncertain about how the program accounts for density of different cloths.
For a woven material, you can specify density of the fiber and matrix, but how does it "capture" the weight value that is traditionally given in oz/yd^2 for the cloth alone?
But under Ply Materials ("Laminate Ply Material Manager")>Create Woven ply, you get the dialog in the picture.
My method is to input for warp and weft each half the density you get considering the raw fabric thickness and area density, such as 5oz/yd^2. The balance coefficient k, I assume, is...
Using NX7, and my question is about locating and specifying laminate properties. I am new to NX, but not to CAD and I have sifted through the documentation plenty.
When defining a woven laminate ply material, NX makes you specify the warp and weft independently as two different materials...
