Thank you Mr. Bulat and Mr. Doyle,

My relaxation data is Stress vs Time, and I am aware of how to curve fit it in the Engineering Data.

But, I also have already curve fitted an hyperelastic model to define my material using Ogden. As far as I am conserned, it is not possible to perform 2 curve fitting in the same material in the engineering data. Please correct me if I am wrong.
