I'm working on a project and I need to model creep behavior of a polymeric material. I have creep data from experiments but not stress relaxation data. I'm aware that the prony series are used in workbench. I have two questions:
1. Does workbench have other viscoelastic models like the Maxwell or Kelvin model?
2. How can I use creep data to perform a curve fitting for the prony series to model the material behaviour?
