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.

This model example illustrates applications of this type that would nominally be built using the following products:
