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。
In simple tension experiment, the stress-strain relationship submits Hook's law within the limit of proportionality.
本文在推导均衡光弹性复合材料应力(应变)—光定律的基础上，导出了均衡光弹性复合材料的近似应变—光定律。
Based on the stress (strain) -optic law derived from balanced photoelastic composite materials, a new approximate strain-optic relation for photoelastic analysis is pro - posed.
如果我们先弄清两条技术术语“应力”和“应变”，从数量上来研究虎克定律就很容易了。
It will be easier to deal with Hooke's Law quantitatively if we pause to define a pair of technical terms: "stress" and "strain".
文中还利用新的角应变定义证明了转轴公式，组成了应变张量和证明了剪切虎克定律。
Using this new definition we deduce the transformation formulas for the rotation of coordinate axes, erect the strain tensor and verify the Hooke's law...
