thermal stress

[Dan_Margulius]

Hello,

I ave a thin plate wich is welded to something that heats the plate to 400 degress. I would like to see the thermal stress in algor but

everytime I get the following error :

MATERIAL ID # =                                   1
  MATERIAL TEMPERATURE =                            0.0000E+00
  CHECK THE THERMAL CONDUCTIVITIES :             
    AT LEAST TWO OF THEM MUST BE > 1.0E-09       
                                                 
Error.  
 

The plate is thin and round  and I applyed thickness 1.5mm and 400 degrees on one of the faces. What else needs to be configured ?

Thanks,

Dan

Hi, Dan,

your problem looks like a problem about structure stress analysis, instead of heat transfer.

If yes, you should go MES directly, select thermal-elastic material model, input material properties, apply temperature load and constrain. Then you can get the stress caused by thermal load.

Algor also provides thermal-MES coupling analysis.

1.) do heat transfer analysis for temperature distribution;

2.) import above temperature distribution to MES analysis as the thermal load

hope it helpful.

Hello,

I am unable to configure it right. I went to MES element definition configured the material as thermoelastic and configured the thickness as 1.2mm, from thermal I configured 400 degrees . I meshed it as plate mesh quite fine and from analysis parameters

I configured " model only" and 0 degrees.

My analysis stops at the first time step. If I add surface temperature 400 degrees on one sideof the plate and fixed constrain on the same face the analysis also stops at first time step.

Can i send you the file to see where i am wrong ?

Thanks,

Dan

To share your model here is the most efficient way for us to solve your problem, I guess.

I am attaching all the files that Algor built.

Thanks,

After looking through your model, I found you didn't set material properties for the part.

As shown in the picture, after being assigned one of material in the material lib, the model runs fine.

Thank you for the solution.
