Greetings all,

I am trying to use gerenalized maxwell viscoelastic model for polyimide polymer films (Kapton) in MSC Marc (or ABAQUS). I have never used the prony series representation of the maxwell model (hereditary integral approach). Has anyone ever used MSC Marc to incorporate the prony series relaxation to the material? or ABAQUS? Here is my game plan for doing this:

 1. I have the uniaxial relaxation curve for the polymer film, I obtain elastic modulus as a function of time for this model by curvefitting the relaxation curve and then obtain the prony series coefficients.
