    Hello,

    I am hoping someone here on this group has used the Johnson-Cook
    material model in either LSDYNA or DYTRAN.

    This material model requires Temperature input. Does anyone know
    what the units for temperature should be? Specifically, the temperature dependent parameters are: Melt Temperature, Room Temperature,
    and Specific Heat.

    I have run test models with Fahrenheit, Celsius, and Kelvin, all with slightly different results.

    Thanks in advance.

    Hi, do you know how to change initial temperature for Johnson-Cook model? I want to run simulations in different temperature.

    Thanks!
