Viscoelastic and linear elastic comparison

Hi Dr.Jorgen, 

I am working on simulating quasi-static contact between a metal and a polymer gear in Abaqus. I wanted to use the viscoelastic model. So I performed DMA in frequency sweep mode to determine the prony series. I compared the results of the linear elastic model and viscoelastic model. They return the same value. The values are the same for both low loads and high loads. So, I am not sure whether this is a proper result or some error in the model.
