stress state and strain state的意思|示意

The variation of stress state and strain state induced by tunnel shield driving in soils is studied, and the variation of soil mechanical properties is studied too in this paper.

本文主要研究隧道盾构掘进施工中周围受扰动土体应力状态和应变状态的变异，以及由土体应力状态和应变状态的改变引起土体力学性质变异的特性。

Plane strain state is familiar in geotechnical engineering, and estimating the principal stress in the plane strain state is very complicated.

土的平面应变是岩土工程中常见的状态，其中零应变方向的主应力是十分复杂的。

Evolution of rock joints into transfixion is described by the time series from strain-stress curves, and the state of joint system in sandstone is chaotic before its ultimate state.

形成岩石全应力应变曲线的时间序列反映了岩石内部节理裂隙趋向贯通的演化进程，砂岩节理裂隙系统在峰前阶段处于不同程度的混沌状态。

Because of complexity of geometric shape and loading state for general component, it is difficult to gain theoretical solution to the state of stress-strain for cracking tip.

由于一般构件的几何形状和荷载状态复杂，难于对裂纹尖端的应力应变状态得到理论解。
