Allowable stress value SH2

Hi all,
I am new to CAESAR II , and my doubt may seem simple to many .

I am working on a line which has a MOC of SA 333 Gr 6. The temperatures being 75 and -46 degree C. My doubt is - In the CAESAR II allowable stress the value of SH2 shows a value of 0. Can someone explain me why its showing so ?

Thanks

Check that entry in the material database, using the "Database Editor".

THANK YOU

Hi all,
To continue with the doubt, if the value of stress is 0 , then how can we get the thermal stresses at that temperature ?


Thanks

You get thermal calculated stress but allowable stress with Sh=0.

This is due to code allowable material temperature. B31.3 allow A333 Gr 6 to use -45 Deg C. You are using -46Deg C hence allowable stress is coming zero automatically.
For stress calculation it will take minimum value of all Sh to compare stress value.
You can manually chane Sh2 value 137.892 n/mm^2 then stress check will be OK.
Please get confirmation from material supplier that material stress allowable will be same upto -46 Deg C since it is exceeding code limit.
