Hello,

in the RADIOSS reference guide (2017, page 328) they say the material law 25 contains strain rate effects.

In the Tsai-Wu yield criterion, where the strain rate acts, the strain rate only influences the yield strengthes.

How do i get strain rate dependent elastic stiffnesses?

Thank you very much!

Kind regards

Tim Winkler
