deviator stress 中文意思是什麼
deviator stress
解釋
偏斜應力-
The study in the paper starts with beam distortions, and it treats the plastic deformation area as pure bending sect, rest of the beam as rigid bodies. according to different shapes of the external tendons, it divides into three structural forms familiar in projects, that is the beams with no deviator, with a deviator and with two deviators, and studies the relation between the deformation of the external prestressing tendons and that of the beams, and derives the formulas of the ultimate stress increment of external tendons. in the formulas, the ultimate angle corresponding to half of the plastic deformation area is considered as a variable parameter
本文首先從梁極限狀態下的變形入手，將塑性鉸區看作純彎段，將塑性鉸以外的區域看作剛體，按照體外預應力筋的形狀不同，分工程中最常見的三種體外結構形式，即無轉向塊的直線型體外筋混凝土梁、具有一個轉向塊的單折線型梁和具有兩個轉向塊的雙折線型梁，研究體外預應力筋變形和梁體的變形間的關系，推導出以極限狀態下塑性鉸區之半對應的轉角為參數的計算體外預應力混凝土簡支梁以及連續梁的體外筋應力增量計算公式，並進一步求得梁的極限承載力。 -
The latest experimental results of rock creep were used : the third invariant of deviator stress tensor had greater effect on creep properties ; the stress threshold of lateral creep of rock was 20 % ~ 40 % less than that of axial creep of the same rock
文中應用了課題組近期巖石流變實驗研究的結果：應力偏量第三不變量對巖石蠕變影響顯著；巖石側向蠕變的應力閥值比軸向蠕變應力閥值低20 % ~ 40 % 。 -
According to the test results of localization and shear bands formation under the consolidated undrained plane strain compression tests on soft clay in shanghai, it was found that the deviator stress of shear band beginning to form was very close to its yield point in clay soils
摘要根據上海軟土在固結不排水平面應變壓縮試驗條件下應變局部化和剪切帶形成的實測研究結果，發現粘性土剪切帶開始形成的偏應力為其屈服點。 -
Based on the duncan - chang e - b model, which can simulate earth - rock dam ' s non - linear mechanics behavior well, the paper introduced the nature coordinate system to the stress space. in this way, hydrostatic stress and stress deviator were decomposed each other. therefore, a partial derivative formulation about displacement and parameter in finite element evaluation was derived in a closed form
論文以能較好模擬土石壩非線性力學行為的duncan - change - b模型為基礎，通過引入應力空間下的自然坐標系，分解應力球量與應力偏量，從而導出一個在有限元計算中，位移對參數偏導數的閉合形式公式。
