ANSYS Viscoelastic (TB, Prony or EVISC)

Test ID  

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.    
Included Tests  
# Test Id Test Name
1x M-611 Stress Relaxation/Creep Compliance by Time Sweeps
Measured property data and model parameters are provided.  
2 - torsional DMA specimen [details]
This model characterizes the viscoelastic response of a material as a function of time.
