Why Miters Matter

[jaybeeboston]

Came across this while doing idle research on brazing & fluxes. Really interesting demonstration of how a small difference in gap has a pretty dramatic influence on tensile strength. Will remember this as I'm coping the next tubes.

Looks more like a chart for brazed lap joints.

Lacking filler type or joint design. Andy

[Mark Kelly]

It's a demonstration of the effect of plastic constraint, which is pretty well independent of filler type or joint design except for where the left hand side tails, which is highly dependent on the ratio of surface energies* of the filler metal and the work surface.


* Surface energy is the phenomenon that governs wetting.

Is there any good theoretical explanation of this? I don't mind a long read (like a book or a couple). I can roughly see where this may come from in a lugged joint but not a fillet brazed one.
