Von Mises Stress Problem


while doing this exercise, no matter how fine mesh I adapt for point 2 the achieved von mises stress is way too higher than the given one, I am having a doubt on the von mises stress given for point 2. Because from point 1 to point 2 its decreasing drastically again from point 2 to point 3 its increasing drastically. So is the provided value of point 2 for von mises stress correct?

Thank You

Hi @redwanpranto15,

Tagging @jousefm who may be able to help you resolve this issue.




Hi @redwanpranto15!

You may have a look at the validation reference here: Spherical Pressure Vessel - Thermomechanical Analysis. On the bottom you can see the plots for the temperature and the von Mises stresses.

Tell me if that helped!




Thanks for the reference, I have reviewed it and it seems that I need to check my simulation and simulate again.
