Hello,

 

In material card for Johnson-Cook formulation, how I active the Iflag option to 1?

 

The helping for the new card  /MAT/LAW2 shows an option to change the Input type flag, but in file Runname_0000.rad, this option isn't available. 

 

I'm using Radioss V14.

 

Thank you!

    When Iflag is 1 simplified input type is active. You can activate this flag in HyperCrash.

    Hi George, thank you for your answer.

     

    I have reviewed the Johnson_plast card in my software HyperCrash V14.0 and I don't find the Iflag. What is your HC version? Do you know about I don't have this option and How I could have it? 

     

    Thank you again.

    Hello,

    I'm using HyperCrash 14.110 version. If you have access, then please update.

    Else, Iflag will be 0, which is default and enter plasticity yield and hardening parameters.
