Dear Community,

 

How do I apply material temperature (T) and transition temperature (T0) in the Johnson-Cook material model?

MATX02 CARD in Optistruct

    The MATX02 card is an old way of running NL, but converting and running Radioss in the backgroud, which allows thermal effects in JC model.

     

    In OS for implicit, I believe you don't have access to JC with temperature. But you could provide some temperature varying properties, with MATTx cards.

    i.e: E varying with temperature.

    For NL analysis, you can use MAT1+MATS1 and assing different curves by using TABLEST (temperature varying elasto-plastic curves)
