Hi everybody,
I am trying to model laminate composites. The geometry has "L" shape with 90 degree angle between two parts (horizontal an vertical parts). As I define anisotropic stiffness matrix, the global coordinates are valid for, lets say, the horizontal part. The other part (vertical) of the geometry, however, rotated 90 degree, and the stiffness matrix must be updated for this part, because the thickness direction is rotated 90 degree.
How should I define this change in directions in my stiffness matrix? In fact, I need to define the local normal-tangential coordinates, which helps stiffness matrix to know the correct coordinates for each part. Any help would be highly appreciated.
Thanks,
Shawn
