In the Manual it says ABAQUS will calculate the Prony series parameters automatically from relaxation test data. Does anyone give some clues of how to do it?
Thanks in advance,
In order to use the time domain viscoelastic material model in ABAQUS, one needs to have the following Prony series parameters:
1. normalised shaer relaxation modulus (gi)
2. normalised bulk relaxation modulus (ki)
3. relaxation time (tau i)
Assuming there is only the experimental data of an...
