英语翻译
As stress increases,some point in the linear relationship is finally reached at which the
material begins to yield.This yield point,Y,of the material can be identified in the
figure by the change in slope at the end linear region.Beacause the start of yielding is
usually diffcult to see in a plot of test data,Y is typically defined as the stress at
which a strain offset of 0.2% from the straight line has occurred.The yield point is a
strength characteristic of the material,and it therefore often referred to as the yield
strength(other names include yield stress and elastic limit)

屈服强度,又称屈服应力或弹性极限,是材料强度的一个指标.我们知道当我们对某一直线型的物体施加一定压力后,材料会弯曲.因为对于材料具体开始变形的瞬间在数据上很难具体的判断,所以我们通常利用材料前点和后点之间形成的角度来判断屈服强度.当角度变化到达百分之零点二时,所施加的压力即为该材料屈服强度.

压力的增加，一些点的线性关系，终于在这次会议上达成
材料开始屈服。这屈服点坐标，该材料可确定的
数字的变化，坡年底线性区域。 Beacause开始收益是
通常难看到在一块试验数据， Y是通常定义为应力
其中应变偏移0.2 ％直线发生。的屈服点是
强度特性的材料，因此它通常被称为收益率
强度（其他名称包括屈服强度和弹性极限）
