Contours of equal moduli
Contours of equal moduliFor Ex , Eq. (4.2.17)
Material properties of Graphite Epoxy from Ex. 4.2.1. Can you see what they are?
What sanity checks can you apply?
4.2.3 Optimization of stack thicknessesUsually, we do not maximize stiffness or strength for given thickness, but instead we minimize thickness for required stiffness or strength. Why?Furthermore, often the ply orientations are given, and the only question is how much of each ply should we take.We mentioned test data as a reason to use only certain ply angles (like 0,90,45), but continuity between panels in wing or fuselage structures is another reason.
Example 4.2.5 from another angle
Contours for different material, but
Check on thickness with the other graphite/epoxy
