how to set model temperature
how to set model temperature
(OP)
I have one small question. I'm trying to demonstrate material non linearity due to temperature.
In other words, I want to show that for the same force, the stresses in the material may be different due to the temperature of the object. Now, I figured the commands for the material property part, but what I can't figure out is how I set my model to have a specific temperature. I tried using the da command (eg: da,1,TEMP,50) but it showed no effects whatsoever.
Do you have any tips for me?
Thank you and every help is much appreciated.

What I was planning to do is this: First I set the material property commands:
MPTEMP,1,0,400
MP,EX,1,12E6,-8E3
TB,BKIN,1,2
TBTEMP,0.0
TBDATA,1,44E3,1.2E6
TBTEMP,400
TBDATA,1,29.33E3,0.8E6
/XRANGE,0,0.02
TBPLOT,BKIN,1
What I'm trying to achieve by this is set 2 material properties for different temperatures, and every temperature in between solves itself out due to the -8E3 tangent.
I didn't consider your body force idea, will delve into the help file to see if i could apply this for the area of the model, give it a set temperature and demonstrate that when I vary this temperature the stress varies according to the material property table.
thank you for the tip, much appreciated

If I may, I've got another small question. As you probably noticed by now my assignment is about material non-linearity, and I thought a good example would be a circlip being pulled apart.
My problem in this case is how I can simulate the boundary conditions effectively, as in real case there's nothing fixed when pulling the circlip from around the tube or pipe.
I included a picture of the circlip should you require it. Thank you.
