Could someone send me a list of sources on modeling a cantilever beam where the beam length is along the z-axis, there is a set of nonlinear forces applied to the beam in both the x and y directions and the beam is spinning clockwise about the z-axis. I am having trouble finding a good numerical model for this system. Any info will be greatly appreciated. Thanks :) -- Peter J. Miles Once a Marine Always a Marine pmiles@eecs.wsu.edu Semper Fi !!!!

If dynamic, the approach is likely to be an eigenfunction model, with each mode excited by the non-linear forces. Another approach is the finite-element model, with a mesh of interconnected nodes and forces at the appropriate node points. I'm not current on the texts or literature.
