Materials Science Formulations
Reduction in Area (%RA)
%RA = ((A₀ - Af) / A₀) * 100
Diameter (d)
d = 2 * sqrt(A / π)
Reduction in Area (%RA) is a standard measure of engineering ductility, indicating how much a metal can plastically strain before cracking.
Brittle materials (like cast iron) exhibit near-zero necking and fail abruptly with very low %RA.
