The role of material damping in the stability of rotating systems

In this paper we consider a whirling shaft, modeled as an elastic continuum subject to general descriptions of the initial conditions and broad descriptions of the boundary conditions. We show that for this class of dynamic systems material damping tends to destabilize the system when the impressed...

Description
Summary:In this paper we consider a whirling shaft, modeled as an elastic continuum subject to general descriptions of the initial conditions and broad descriptions of the boundary conditions. We show that for this class of dynamic systems material damping tends to destabilize the system when the impressed angular velocity exceeds the fundamental critical velocity of the system.
