Viscoelastic Maxwell - *mat model in LS-Dyna

Hi, everybody!

Im solving problem concerned with high rate deformation of viscoelastic material. For this porpose Im using LS-Dyna and I need to take into account temperature effect on VE material. Could smb suggest me which material model available in LS-Dyna to use. From theory manual I have found so called model#175-Viscoelastic Maxwell (obviously this is generalized Maxwell model) (which consideres Proney series for describing relaxation function and WLF equation for temperature effect). Unfortunately I did not find discription of this card in the keyword manual (ver. 970). I would be very appreciated for any help, probably smb could write me here discription of this card or perhaps smb could suggest me another material model.

Thx in advance!
