materjali plastsusnäitaja; tõmbeteimiku suhteline ristlõikepindala muut purunemiskohas tõmbeteimil (vt ahenemine; vrd katkeahenemine/protsentuaalne ahenemine)
Hea teada
Suhteline ahenemine on leitav kui (So - Su)/So, kus So on teimiku algristlõkepindala, Su - teimiku lõppristlõikepindala.
the difference between the original cross-sectional area and the smallest area at the point of fracture of a tensile specimen (see: cross-section reduction; compare: percent reduction of area)
Hea teada
Reduction of area is calculated as (So - Su)/So, where So is original cross-sectional area and Su - cross-sectional area at fracture.
