Bending and Torsional stiffness of Closed Profile hat/Omega stringer
Bending and Torsional stiffness of Closed Profile hat/Omega stringer
(OP)
Hallo Engineers,
I am a little bit confused here and i need some guidance.
Can any of you educate me on how to calculate the Bending and Torsional stiffness of a Hat/Omega stringer attached on a plate to form a fuselage panel?..You can also recommend to me a book where it is clearly described so that i can get in-depth with the topic.
The material is Aluminium by the way.
Thank you guys in advance, i will really appreciate the help.

RE: Bending and Torsional stiffness of Closed Profile hat/Omega stringer
Torsional stiffness of thin walled closed tubes of arbitrary shape with varying wall thickness is not as simple as using an equation, if you want a result that is meaningful. In your case identifying the axis of rotation is tricky. Once you find it then just add the torque contributions of the shear stress. Again Bruhn is probably a good place to start. Or FEA.
