Stiffness matrix for 3D circular beams and conical tubes.
Stiffness matrix for 3D circular beams and conical tubes.
(OP)
I'm looking for the 3D stiffness matrix for a 3D circularly bent (or elliptical) beam.
Also for a conical, thin walled tube.
I found an article from 1985, and I think there are a few errors in it, so I want to compare.
Are there any good, more recent sources for this kind of info?
Are there any handbooks for stiffness matrices around?
