23.3Understanding composite layups and

orientations

The orientation of the bers within each ply of a composite layup

plays an important role in determining the physical qualities of your

model; however, dening this orientation in a model based on a

real-world application is not straightforward. Composite layups in

Abaqus/CAE make the process more manageable by deriving the

orientation of the bers from three parameters that are relative to

Abaqus projects the specied orientation onto the surface of the

shell, aligning the direction of the layup orientation that you choose
