✦ Synopsis

The paper is concerned with the dissipative behavior due to multi-frequency excitation. It is shown both theoretically and experimentally that it is possible to treat the frequencies separately. Practically, this leads for instance to the conclusion that the material damping in a rotor with anisotropic bearings can be treated as a complex stiffness, which simplifies the calculations dramatically.
