What this part means
Divide the expression above the line by the one below it.
Its job in the formula
The expression above the fraction bar is divided by the complete expression below it. The denominator must not be zero.

The passage around this formula
The mechanical-metamaterials case sharpens the same point from a different angle. A computationally designed lattice — an octet truss or similar architected structure — can be optimized in silico for a target stiffness-to-weight ratio, and DFT-adjacent atomistic methods can predict the base material’s elastic constants reasonably well. Whether the as-manufactured lattice reaches that target depends on print-defect statistics, strut-level stress concentration, and fatigue behavior under cyclic loading that only a physical tensile or fatigue rig captures, because those failure modes emerge from manufacturing variance and load history, not from the unit cell’s idealized geometry. This…

A fraction a/b means a divided by b. The top number is the numerator; the bottom number is the denominator, and it cannot be zero.
