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.
