等应力 meaning in Chinese

equal stress
isostrain

And with reinforced concrete finite element a simulation calculation method is founded for randomness of initial cracks within the equal stress zone of concrete members
结合钢筋混凝土有限元，建立了混凝土构件等应力区初始裂缝随机性的仿真计算方法，对钢筋混凝土梁纯弯段的裂缝规律进行了仿真计算。
6 with the optimization of the mix proportion of hprrc and with the old concrete was repaired with hprrc whose strength is close with that of the old concrete , the stress - strain curves of new - old concrete is tested on ordinary testing machine and mts . the results show that under equal stress conditions , the ratios of the strain of old concrete , hprrc to new - old concrete are 82 . 4 - 105 % on ordinary testing machine and 90 - 121 . 3 % on mts respectively
6 、通过优化hprrc的配比，用与老混凝土强度接近的新混凝土对老混凝土进行修补后，在普通试验机和mts试验机上对新老混凝土的本构关系进行了试验研究，结果表明：在等应力条件下老砼、 hprrc博士学位论文.中文摘要的应变与新一老硷的相比，应变的比率在普通试验机上为82 . 4一105 % ，在川、 s上为90一121 . 3 % ，即三者变形是基本接近的。
