Eigenmodes of a Viscoelastic Structural Damper

Application ID: 75931

In this example, the eigenmodes of a structural damper are computed.

In the damper, most of the deformation is controlled by the viscoelastic domains, which have strongly frequency-dependent stiffness and damping properties. This leads to a nonlinear eigenfrequency problem, which must be solved by iteration for each individual eigenmode. The procedure is automated through the use of model methods.
