Delamination

2 essays name this object, across one field. What follows is each of them, and the objects they name alongside it.

Also named here as shear connection — the same set of essays touches all of them, so they are one junction rather than several.

The shear nobody draws

A stack of loose planks slides at its ends when it is loaded. Glue them and the sliding stops — and whatever the glue is now carrying is a stress that no bending calculation contains.

The section made of pieces

Two plates bolted together are twice as strong as one plate. Two plates made to act as one section are eight times as stiff. The difference is entirely in the joint, and the joint has a calculable spacing.
