Abaqus viscoelastic material properties

When Abaqus is the selected solver, you can define frequency-dependent or time-dependent properties for representing the dynamic behavior of materials such as glasses, rubbers, and high polymers under stress. For isotropic, orthotropic, anisotropic, and hyperelastic materials, Time and Frequency options are available on the Viscoelasticity tab in the Materials dialog box.

These types of material properties let you analyze situations in which the strain rate has a significant effect on the material response.

The following domains are supported:

• Time — Creep Test Data, Frequency Data, Prony Series, and Relaxation Test Data definition options.

• Frequency — Creep Test Data, Power Formula, Prony Series, Relaxation Test Data, and Tabular definition options.

The Viscoelastic properties correspond to the parameters for the *VISCOELASTIC, *SHEAR TEST DATA, *VOLUMETRIC TEST DATA, and *COMBINED TEST DATA keywords in Abaqus. For more information, see the Abaqus Keywords Reference Manual.
