ANSYS Viscoelastic (TB, Prony or EVISC)
This TestPak is used to model the response of an incompressible material when it is important to include dissipative losses due to viscous (internal friction) effects. DMA Stress Relaxation experiments are performed at multiple temperatures; time-temperature superposition is used to develop a shear modulus vs. time master curve. The data is fit using Prony coefficients.

This model characterizes the viscoelastic response of a material as a function of time.
