I am analysing a 10" Stub Acme studded connection which is thick-walled. The connection has drilled holes which don't penetrate through the vessel wall and is subjected to internal pressure.
I am unable to use ASME 2007, Section VIII Division 2 Part 4.3.9 because the connection is thick-walled...
I have been unable to find the Sm (design stress intensity) value in the tables of the 2004 ASME BPVC Section II Part D for a particular material, namely AISI 4140.
Can you calculate the Sm value based on the Yield Strength of the material?
