For obtaining the numeral solutions of round elastic plates in axisymmetrical deformation with varying - thickness in nonlinear deformation in the unsteady electromagnetic field and mechanical field, by establishing the equations of motion, the equations of distortion, the equations of lorentz force, the equations of electronic dynamic mechenical, and adopting iterative method, we gained the nonlinear magneto - elastic calculation method and outcome of current - carrying shell, and gained the influencing degree toward mechanical parameter of varying thickness round ferreous plates in the electromagnetic field and mechanical field
摘要為了獲得內邊界固定的環形導電薄板在均布力與橫向磁場作用下的變形問題的數值解，通過建立運動方程、變形方程、電動力學方程和洛侖茲力方程，運用迭代法得出了載流板殼的非線性磁彈性的計算方法和結果，以及機械場、電磁場對鐵質變厚度圓板各力學參量的影響程度。Soil springs are used around the pipe including vertical, lateral and axial soil springs to consider the interaction between the pipeline and the surrounding soil. the pipe segment near fault that usually suffers large deformation is modeled with a plastic shell element in order to consider the effect of local buckling and section deformation. to reduce the calculating time of the whole model, an equivalent spring proposed by the author is applied at two ends of the shell model
為了解決現有的殼單元方法需要大量計算機時的缺點，本論文首次從理論上把離斷層較遠管土之間相對變形較小的管子直線段部分的變形等效為一個非線性彈簧，將此等效邊界引入到有限元模型中，使得模型中的殼單元部分主要用來分析我們所感興趣的在斷層附近發生大變形的管段，從而達到節約計算時間的目的。In the case of 16 boundaries, cubic b - spline function taken as trial function, the solutions to nonlinear stability of truncated conical shells and spherical shells with variable thickness were obtained by the method of point collocation
在16種邊界條件下，以三次b樣條函數為試函數，用配點法計算變厚度開頂圓錐殼和球殼的非線性穩定。Under action of uniformly distributed load or line load along inside edge, the upper and lower critical loads of truncated spherical shells with exponentially variable thickness and rigidly clamped edge were consistent with those obtained by other methods
在均布荷載或內邊緣均布線荷載作用下，指數型變厚度固定夾緊開頂球殼的上、下臨界荷載得到了同其他方法一致的結果。Under action of uniformly distributed load, line load along inside edge or uniform moments along outside edge, upper and lower critical loads of truncated conical shells and spherical shells with linearly variable thickness were computed
出了在均布荷載、內邊緣均布線荷載或外邊緣均布力矩作用下，線性變厚度開頂圓錐殼、球殼的上、下臨界荷載。分享友人
