What is the concept of \"allowable stress intensity Sm\"?
Thread Content
How is the \"allowable stress intensity Sm\" determined? What is its relationship with tensile strength, yield strength, or allowable stress? Thank you all
Consult the mechanical design manual and JB4732
Why go the extra distance? See GB150, page 5
3# Is there no moderator for JFTANG726? Where is it? There is standard tensile strength, standard yield strength at room temperature, yield strength at the design temperature, endurance length, and creep limit – that’s all. Thank you
I feel like the allowable stress mentioned at 150 is just the allowable stress intensity Sm referred to by the original poster, with only a different notation
Back to upstairs: It’s not the same concept. I found some information related to this; the stress intensity is the maximum stress minus the minimum stress, That is, sigema1 minus sigema3. But what about the allowable stress intensity?
Both the allowable stress and the allowable stress intensity are properties of the corresponding material. The term \"allowable stress\" is used in GB150, and it is based on the first strength theory. The allowable stress intensity, on the other hand, is mentioned in JB4732; it is based on the third strength theory.
