應力變化-
The coupled effect is analyzed for an elliptical inhomogeneity under plane uniform loads and linear temperature change at infinity. the complex potentials are obtained for an elliptical inhomogeneity under plane uniform mechanical loading, uniform temperature change and uniform heat flow directed at any angle. the discussion is also given to the variation of the interfacial stresses with thermal parameters
分析了無窮遠平面加載和線性溫變的耦合效應，獲得了橢圓夾雜體在無窮遠平面均勻加載和均勻升溫以及任意方向的均勻熱流共同作用下的復勢解答，並討論了界面應力隨各熱載參數的變化規律，發現基體導熱性能越好（與夾雜相比） ，界面應力幅值越大。 -
This variation of stresses is due to the action of in - plane shear strain in the plate, which is termed “ shear - lag ”. stresses larger than the elementary bending uniform stress thus develop at the web - flange connection. an appropriate reduced “ effective width ” of the plate - with the uniform stress equal to the maximum longitudinal stress - has been widely used by engineers in conjunction with the elementary beam bending theory
但實際上翼緣中剪切變形是不均勻的，由此導致正應力沿橋寬呈曲線分佈，從而引出了有效寬度的概念，即按初等梁理論的公式也能得與真實應力峰值接近相等的那個翼緣折算寬度。 -
Compared with phase - shift control, pwm plus phase - shift control can reduce the current stresses and rms currents of the converter. the loss of the converter can also decrease. lt is proved the converter can achieve zvs in larger load variation
與常規相移控制方式相比， pwm加相移控制方式能減小變換器的電流應力，減小通態損耗，同時也能拓寬零電壓開關的范圍，使變換器在較寬的負載變化范圍內都能實現軟開關。 -
Through studying the cptu chamber test with the soil as a medium in door, according to the stress which generated in the course of probe penetrating, include axial additional stress and radial additional stress, measured by subminiature pressure cells which buried in the soil. this paper analyzed the rule of variation of axial and radial additional stresses, and compared with each other
摘要通過以粘土為介質的孔壓靜探（ cptu ）模型槽試驗研究，根據埋置在土中的微型土壓力盒在貫入過程中所則到的土應力（軸向附加應力和徑向附加應力） ，分別分析了軸向和徑向附加應力的變化規律，並進行了比較。 -
The disturbance mechanism and characteristics of soil and its influence extent induced by pipe jacking are studied. the variation of stresses and properties in the disturbed soil during jacking process is also analyzed
對頂管施工擾動的機理及其特徵、擾動的影響范圍、擾動區土體的應力變化、擾動區土體的性質變化等進行了研究。 -
Finally, the technic route for the research of milling distortion is proposed. in chapter 4, the effect of tool path and clamping schemes on residual stresses as well as machining distortion are analyzed by using three - dimensional elastic - plastic fem ( finite element method ). the distortion variation tendency under four typical tool paths, the pressing - plate clamping and stretched fixation is obtained respectively
第四章基於上述理論基礎，利用三維彈塑性有限元技術分析了走刀路徑和裝夾方案對銑削加工殘余應力分佈和變形的影響，得到了四種典型的走刀路徑以及壓板式裝夾和拉伸裝夾對加工變形的影響趨勢。
