To validate the formulated transition element for the calculation of the hot - spot stress and stress concentration factor in the welded components by experimental results, the stress concentration factor of the experimental welded specimens carried out in the research group is calculated by using the developed plane - transition element. the calculated stress concentration factor in the two types of tested welding components agrees well with that obtained from the experimental result. and the calculated result on the tendency of hot - spot stresses agrees well with that from the measured result
為了驗證文中構造的過渡單元模型用於分析焊接節點附近的應力集中問題的正確性和有效性，進一步又對過渡單元模型進行實驗結果驗證，採用平面過渡單元模型計算了本課題組進行的兩類焊接構件的應力集中系數，並與根據實測方法得到的應力集中系數進行了比較，計算結果與實驗測試得到的應力集中系數和相應的熱點應力變化趨勢比較吻合，為本文建立的過渡單元的實際應用提供了初步的基礎。 -
Many cases of excavation and support of high rock slopes were symtematically analyzed, and some conclusions were drawn. there exists stress concentration in grading angle induced by excavation and obvious change of stress and strain on sloping surface, which reduce as the increase of distance to surface. initial stresses have important influence on excavation and support
撇面上的應力應變的靴很大，隨著離坡面距離的增加而減小；初始地應力對邊坡的開挖支護產生很大的影響，隨著初始地應力的增加，開挖坡面回彈位移增大。 -
Numerical results show that the bubble concentration distribution can be predicted by using the two - way coupling of the fluid and the bubble motion, and adding the wall lift force into the bubble motion equation, and the fluid velocity, turbulence intensity and shear stresses modified by the bubble motions can also be revealed
