how to model the damping behavior of viscoelastic passive damper using ANSYS applied to a sandwich beam

 

 dear all, 

How can I model the changing
relationship of shear modulus with frequency for a passive constrained viscoelastic
damper used as part of a composite  sandwich beam which is subject to a walking
excitation using ANSYS ??

 This is for a 3-layer sandwich type simply supported beam with core layer sheet viscoelastic type damping, which is Butyl rubber. The beam is subject to walking load excitation.  I do have storage shear data from a dynamic test but ANSYS wont allow non-linear material models (prony series) in a harmonic analysis, so what can i do?

hey,,,,,,,,,,,,,,,,if u hv already done tat project means pls send me details,,,,,,,,i am carrying out same project,,,,,,,,,,,,,sreensree1014@gmail.com
