Shear capacity formula - austenitic stainless steels
Shear capacity formula - austenitic stainless steels
(OP)
I'm trying to scour for some way of calculating the shear capacity of 304L stainless steel sheet. BS5950 doesn't cover it, neither does the BSSA (british stainless steel assoc), or the SCI. I have read through any relevant publication I can find on their sites.
I have checked through tables of the larger stainless suppliers like Eurosteel but they dont give shear capacity for thin sheet either. There must be some way to calc it?
I saw a previous similar thread for a different grade stainless steel, where this relationship relationship was used:
? = 0.6 ยท ?
where
? is the shear strength
? is the tensile strength
In the previous post it was mentioned austenitic materials have different strain hardening properties than the formula above. Is there any literature I can find a formula for austenitic steel? Any advice is appreciated!

RE: Shear capacity formula - austenitic stainless steels
shear strength = 0.6 * tensile strength
RE: Shear capacity formula - austenitic stainless steels
τ = 0.6*σ
CODE
Go to the Process TGML and follow the code for Greek letters.
RE: Shear capacity formula - austenitic stainless steels
The basis for this formula is the von Mises/Huber/distortion energy failure criterion. This states that yielding in shear occurs at a stress level that is equal to 0.577 times the tensile yield stress.
Due to the variation in strain hardening between slip systems, the natural spread in fracture strength and elongation for a material, and to avoid using more significant digits than are warranted, the 0.577 factor becomes 0.6.
