Thank you @HYK, I would like to model a simple SDOF model with elastomer connected to the ground and an aluminium mass.
Then extract the Frequency Response Function (FRF) in Z direction on the aluminium mass (with a resonance damped by the elastomer loss factor).
I attached a simple FEM model (but incomplete: the elastomer model is not defined as well as the solution to extract the FRF). Can someone help me to create the proper setup?
I attached in a excel the material properties of the elastomer in terms of complex shear modulus (G*) over the frequency range also depited below. Consider Poisson = 0.49, hence E*(omega)=3 x G*(omega).
