reduction of area

reduction of area

[ri′dək·shən əv ′er·ē·ə]
(metallurgy)
In tensile testing, the percentage of decrease in cross-sectional area of a specimen at the point of rupture.

reduction of area

The difference between the original cross-sectional area of a test specimen before being subjected to tension and the area of its smallest cross section after rupture; expressed as a percentage of the original cross-sectional area of the specimen.
