I'm referring the frequency response graph, acceleration vs. frequency.


Howerer, I think that I solved the problem, now it seems to works, but I don't know if it's good.


jjdoyle, you wrote: "Alternatively, as a test, you could also try to define the equivalent the Prony Series alpha and tau values in frequency domain (as a test)."


But I got only experimental results about G' Modulus and Loss Factor, I don't have the shear vs. time relaxation graph. Considering the experimental data the i got, the command that i used it's the correct procedure?

I want to be sure that the procedure is correct, than i try to change the values!

Thank you very much.
