Your “breakage” force is only meaningful at catastrophic failure for determining safety factors.
Perhaps you should look up the definitions of elastic modulus, yield strength, and metal fatigue. While you are at it you you might want to look at breaking strength. All are related to the effect of stress and strain on metals. You get the elastic modulus from the slope of the stress and strain curve below the yield point which you get off the same curve. Rupture, or “breakage” occurs
on the same curve post the ultimate strength point.
If you can get them all off the same curve...like those presented by Pilar Spokes...they are related by definition.
Clue: Fatigue life, yield strength, and modulus of elasticity are all measured independently of ultimate tensile strength at breakage.
No, they aren’t. They are all measured on the same equipment and in the same test. Look it up.
Keep going down your rabbit hole and you’ll soon post something like “Tighten the nipple until the spoke breaks then back off x turns.” HAW!
Non sequitur much?
