In simple tension experiment, the stress-strain relationship submits Hook's law within the limit of proportionality.
摘要单向拉伸试验中，在比例极限内，应力应变关系服从胡克定律。
This value is used to compare the strength of materials, but a safety factor is applied when making design calculations, to bring the working stress well below the limit of proportionality.
此值被用来比较材料的强度，但是当设计计算时，要用一个安全系数，使工作应力低于比例限制。
