materjali plastsusnäitaja, tähis Z; tõmbekatse/-teimi käigus toimunud suurim ristlõikepindada muut, avaldatuna protsentides ristlõikealgpindala suhtes (vt ahenemine; vrd suhteline ahenemine)
Hea teada
- Katkeahenemist arvutatakse valemiga (So - Su)/S0 x100%, kus So on katsekeha/teimiku algristlõikepindala ja Su - katsekeha/teimiku lõppristlõikepindala (peale katkemist).

maxiumum change in cross-sectional area which has occured during the test, expressed as a percentage of original cross-sectional area, Z (see: cross-section reduction; compare: reduction of area)
Hea teada
- Percentage reduction of area is calculated as (So - Su)/S0 x 100%, where So is original cross-sectional area of a specimen and Su - final cross-sectional area of a specimen after fracture.
