viscoelasitk material with ANSYS?

[foransys]

how can I describe viscoelastic material?

[Muzialis]

foransys,

the easiest option is to use the Ansys built in Linear Viscoelastic Model.
The material behavior is described in Prony Series Terms.

Hope this is a useful start

All the best

thank you muzialis,
but, there isn't linear viscoelastic model in material model.
my analysis is nonlineer analysis. in this cause, material model nonlineer viscoelastic.
can you look at file? is it right?

Foransys,

you will find linear viscoelastic models in Ansys named Maxwell and Prony.

To my knowledge ( but do not consider it definitive at all) there are not non linear viscoelastic material in built models in Ansys.

Hope this helps

I can not open the file.

thank you,
give me your mail adres? file send mail adres?okay
