Hi,

I am relatively new to modeling of polymers and I am trying to model a viscoelastic polymer using Generalized Maxwell model.

I have creep test data for the polymer in the form of force v displacement curve.

I wanted to know how to get the parameters for the Generalized Maxwells model.

Thank you.

First, you need to convert the force - displacement data to stress-strain data. Then you can calibrate a viscoelastic material model to that data set. The calibration can be performed using [URL= http://polymerfem.com/content.php?9-MCalibration ]MCalibration[/URL], Abaqus, or ANSYS.
