Create a viscoelastic material model as described in Defining time domain viscoelasticity” or Defining frequency domain viscoelasticity.”
From the menu in the Edit Material dialog box, select Shear Test Data. A Test Data Editor appears.
In the Long-term normalized shear compliance or modulus field, enter either the long-term, normalized shear compliance, jS(∞), for creep test data or the long-term, normalized shear modulus, gR(∞), for relaxation test data.
In the Data table, enter the following data:
- js or gR
The normalized shear compliance, jS(t), ( (jS(t)≥1)) for creep test data or the normalized shear relaxation modulus, gR(t), ( (0≤gR(t)≤1)) for relaxation test data.
- Time
Time, t. (t>0)
For detailed information on how to enter data, see Entering tabular data.
Click OK to return to the Edit Material dialog box.
