Actually i want to know the description of stiffened panels in aircraft i.e its location,loads acting on the stiffened panel,types,damages,stress concentration.
pl help need urgent
Thanks

GS:

Stiffened panels are used all over aircraft from the fuselage to the wings and control surfaces, even in the interior. The loads, types of failures, resultant damages, and stress concentrations are as varied as the types and locations.

If you can identify some specific locations we may be able to give you more guidance.
