Shear yield — where it appears

The shear stress at which a ductile material gives way, which for a von Mises material is the yield stress divided by the root of three.

Named by 2 essays across 2 fields — each of them below, with the objects they name alongside it.

The metal between the holes, which comes out as a block

A bolted end connection can fail without a single bolt breaking and without the plate reaching its tensile strength anywhere. A block of metal simply comes out, bounded by two surfaces with two different strengths on them.

The panel that carries more after it has failed

Everywhere else in this field a critical load is where the argument ends. A thin web is the exception — it buckles visibly, in waves anybody can see, and then goes on to carry nearly twice as much again by turning itself into a truss nobody drew.
