Automated Multilevel Substructuring for Nonlinear Eigenproblems [article]

Heinrich Voß, Kolja Elssel, TUHH Universitätsbibliothek, TUHH Universitätsbibliothek
In this paper we generalize the automated multi–level substructuring method to certain classes of nonlinear eigenvalue problems which can be partitioned into an essential linear and positive definite pencil and a small residual. The efficiency of the method is demonstrated by numerical examples modeling damped vibrations of a structure with nonproportional damping, a gyroscopic eigenproblem, and a rational eigenproblem governing free vibrations of a fluid–solid structure.
