Definitions for "Reduction of Area"
The difference between the original cross-sectional area of the gauge length of a tensile specimen and the cross-sectional area at the point of fracture. This difference is usually then expressed as a percentage of the original cross-sectional area and the result used as a measure of the ductility of the metal being tested.
Measure of the ductility of metals obtained in a tension test. It is the difference between original cross sectional area of a specimen and the area of its smallest cross section after testing. It is usually ex-pressed as % decrease in original cross section. The smallest cross section can be measured at or after fracture. For metals, it usually is measured after fracture and for plastics and elastomers, it is measured at fracture.
The difference between the original cross-sectional area of a tensile specimen and that of the small-est area at the point of rupture. It is usually stated as a per-centage of the original area; also called "contraction of area."
