Hi javat, 

Are you sure you have calibrated the damage variables correctly from the test data?

I am not sure if you can equate the damage variables directly to the JC main model coefficient can you check if the reference you had is from a proper source? A is inherently a yield point and reaching such of level of damage is unusual and incorrect to work. 

Check the following YouTube link for the calibration of the JC correctly with strain rate cases.
