For strain rate sensitive material (e.g., steel), often the Johnson Cook (JC) model is used, in explicit dynamics - see the help manual on that.
(Not sure how to use/convert your data into the JC parameters needed in Ansys - perhaps if you look on the internet or if someone else knows)
Also this is of help:

Thank you for your answer.
I have a stress-strain graph. accept melting temperature and ambient temperature constant. i've stress-strain curve and strain rate, how can I determine the johnson-cook parameters using the data I have.,
I have this one, and also strain rate, may i determine johnson cook parameters. temperatures are constant value.
