algmõõtepikkuse (Lo) suurenemine mistahes katse momendil (vt protsentuaalne pikenemine, suhteline pikenemine)
increase in the original gauge length at any moment during the test (see: percentage elongation, egineering strain at fracture)
Hea teada
The increase in length of a specimen during the tensile test is calculated as (Lo - Le), where Lo is original gauge length, Le - extensometer gauge length.
