Viscoelasticity Constants in Ansys

[faisal]

For Linear Viscoelasticity, ANSYS Workbench needs 2 Constant. instantenous shear Modulus and Viscoelastic Decay. the documentation from ANSYS didnt help much, or rather, i dont really understand it much. could someone explain to me how to obtain these two?

You can get the required values from a simple stress relaxation experiment.
(We do those experiments if you need help).
