断裂伸长率 duànliè shēnchánglǜ
gen.	elongation at break
met.	fracture elongation (【技】材料试样在拉伸试验中被拉断时，测量标距间的伸长量与原始标距长度之比，以百分数表示。试验时用电阻应变片与引伸计测量拉伸变形量，直至试样破坏。从测得的应力-应变曲线中可算出断裂时伸长率。断裂伸长率与材料性能密切相关。韧性好的材料，断裂伸长率较高。)
oil	breaking elongation
plast.	elongation of break; elongation of rupture; extension at rupture; percentage elongation at break
polym.	extension at break; rupture elongation
tech.	crack extension rate
textile	elongation-at-break
wind.	breaking elongation rate
