hello, i really need your help.

i have these information about a Viscoelastic material:

how i can define these properties to Ansys and analyze a Viscoelastic Model?

Hello,

to use a viscoelastic material you should usually (in your case) input the decay constants and shear moduli for the prony series. It seems that your data is not sufficient as you dont have a value for tau.

we have shear response(in post #1) and tau=1s.
is it enough for ansys? can you explain how i can import these datas to ansys?
thanks...

Using a spring-dashpot model (e.g. Generalized Maxwell Model) should be sufficient for your purpose. I am no expert in Ansys but I am sure that there exist these types of material cards that are referred to in the users manual.

I recommend that you find the necessary viscoelastic material parameters using our MCalibration software.
