I get this message when I want to set the matter in Creo 3.0.
Or can one learn this information.
The PTC_TENSILE_YIELD_STRESS parameter is not defined.
The material is not valid.
Are you using an elastoplastic material model?
Thanks for the reply,
I simply wanted to identify the elastic steel.
So in the material definition box for the stress-strain response it says, "linear"?
Denis, please check if you have the stress-strain response set to "Linear".
If that is the case, the system should not complain about yield stress.
I get this message at random times even with sensible material properties.
It seems to occur most often when taking an existing material as a starting point, copying it and then editing the copy.
I may only change the E and nu slightly but it insists that this parameter PTC_TENSILE_YIELD_STRESS is not defined.
So I give up and define the material from scratch and the s/w is happy.
I have been meaning to file a call for a while.
It even happens now and then when you define a new material. No idea what to do about it.
