Shortly describe Lateral buckling (Kippen)
Stability problem which is a combination of bending an torsion
Stabilitätsproblem, das Durch Biegung ausgelöst wird und im Versagensmodus Biegung und Torsion zeigt
How is torsion and biaxial bending introduced in Lateral buckling?
In 2nd order Torsion is introduced by deflection in y (v) (given by first derrivative)
Biaxial bending is given in 2nd order due to the torsional deflection theta
Was ist Kippen auf Englisch?
Lateral buckling
What is Lateral buckling in german?
Kippen
Give the critical Moment around y and the influencial parameter?
Modulus of Elasticity
I around z (in y)
I omega - Warping stiffness
I T - Torsional stiffness
Shear Modulus G
Why is the Moment of Inertia around y not of interest for Lateral buckling (Kippen)?
Because it describes general bending —> Already loaded —> Not a stability issue
Give the differential equations of bending and warping torsion (If loaded with My and fork restraints)
Give the general Critical buckling force for the following loading situation:
(k also dependend on where the Force is applied)
Discuss why the position of the force F has a decisive influence on the maximum load
z_f will be the input for the lever arm for torsional loading of the beam in second order
