有限应变测量（finite strain measurement）是指根据变形岩石中各种应变标志物变形状态的多种测量数据与其原始未变形状态比较，定量给出构造变形区各点岩石的应变状态，求取各点应变椭球体的主轴方位、轴比、弗林指数（k）和应变强度（d）等；进而可建立区域应变场、推算剪切带的剪切位移量和造山带的地壳缩短量等。常用的应变测量方法有长短轴法、Fry法和摩尔圆法等。
本文以纳米压痕法结合量纲分析及有限元方法来测量薄膜材料的应力-应变关系。
In this master thesis, the stress-strain relationships of thin films were measured by nanoindentation combined with dimensional analysis and finite element method.
对一定区域内不同部位的岩石有限应变进行系统的测量就可以得到这个区域内的应变分布图象—应变型式。
Regional strain distribution pictures, strain patterns, may be determined by systematically measuring the finite strains in rock at the various spots in the relevant regions.
该方法是将复合材料的横向剪切弹性模量视作横向剪应变的函数，由横向剪应变的测量值反演横向剪切弹性模量。剪应变与剪切弹性模量间的函数关系用有限单元法得到。
The transverse shear modulus of the composite material is regarded as the function of transverse shear strain, thus the modulus is inVersely computed by the measured values of the strains.
