Using a visco-hyperelastic material in explicit analysis

  Hi,
  
  I am facing issues try to use a visco-hyperelastic material in explicit dynamics. Can anyone assist me with this?
  
  When I use static structural, I am able to successfully develop a visco-hyperelatic material using the "prony shear relaxation" under the viscoelastic tab. However when I switch to explicit dynamics, the "prony shear relaxation" tab is lost. I can only include viscoelastic behavior by going to linear elastic tab. And this doesnt work.

  Prony series is not support by ANSYS explicit dynamics, if you need to use that, you can consider using LS-Dyna.
  
  Generally Explicit dynamics is used to simulate things happened in a very short period of time, for example, milllsecond level, which is different from the time scale for prony series to help.
