about viscoelastic properties modeling

[polymerian]

Hello,

I m facing problem to model the orthotropic Viscoelastic modeling in Frequancy domain. i m using Msc Marc software for this Modeling.
im gone to find the Damping properties of composite material.
Could you help me please.

Thanks for reply Jorgen, Actually the problem is that i have viscoelastic properties of Composite in frequancy domain. but in the Marc software the Viscoelastic Properties input is in Time domain, and i dont know how to model in frequancy domain, also all sub rountains which is given in Marc is define by Time domain.
My target is to find out the viscoelastic damping of composite material.
