Answer:
Stresses cannot be calculated for every orthotropic thickness type.
For the following orthotropic stiffnesses, the stresses are also calculated:
- Orthotropic stiffness type with a constant thickness (Image 01).
- Orthotropic 2D material model with a constant thickness (Image 02).
No stresses are calculated for any other orthotropic surface types. For an orthotropic model with different thicknesses in the x and y directions, the display of the stresses for the x and y directions would be relatively complex and incomprehensible (Image 03).
The three basic stiffnesses are defined in the attached file.
