Implement viscoelastic behavior in abaqus from 3 points bending DMA data

Dear all,
Ive conducted 3 points bending DMA tests on composite material (nat fibers/epoxy) @ different temperatures and frequencies. So I get E, E, tan(delta), and Ive fitted prony coefficient (Eo,Ei,tau_i). Now I want to use them in Abaqus to model dynamic behavior of a simple plate @ different frequencies. Ive checked viscoelastic implementation and I need to input K_i, G_i, tau_i, that I dont have.

Thank you for your help,

Vincent

Edit: as first trial Ill use my flexural stifness prony coefficeint as K_i and G_i
