Bending About the Y Axis

Bending about the Y axis can be seen in 図 1. The equations relating to the moments being produced are calculated by:(1)
M y 1 = f y y ( θ y ) + C y y θ ˙ y
(2)
M y 2 = M y 1

Where,

θ y = θ y 2 θ y 1 is the relative rotation of node 1 and 2.

f y y ( θ y ) is the function defining the force-displacement relationship.
