Design Stress Intesity
Design Stress Intesity
(OP)
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?





RE: Design Stress Intesity
ASME code materials start with ASME SA- "the material spec number"
if you want asme code material, browse through ASME Section II to find a material with the properties you require.
RE: Design Stress Intesity
Can the Sm (design stress intensity) value for non ASME code materials? i.e using 2/3 Sy for example?
RE: Design Stress Intesity
if it's code work...material has to be in section II
if it's not code work....good engineering practices apply or the code you are building to applies.
