Creating a viscoelastic material model

You can define viscoelastic behavior in a material as a function of frequency (for steady-state, small-vibration analyses) or as a function of reduced time (for time-dependent analyses). For more information, see the following sections:

• Time Domain Viscoelasticity

• Frequency Domain Viscoelasticity

• Defining viscoelastic materials
• Defining time domain viscoelasticity
• Specifying thermorheologically simple (TRS) temperature dependence for time domain viscoelasticity

• Specifying volumetric test data
• Specifying combined test data
