A time-domain finite element, model incorporating nonlinear viscoelastic behavior, characteristic of elastomers, has been developed and implemented in a rigid blade flag-lag-torsion analysis. Results show that the nonlinear behavior of the elastomeric damper has a significant effect on lag mode stability in hover and forward flight. The details of damper response in forward flight vary significantly with disk loading and advance ratio.
