The paper establishes mathematics model of electromagnetic heating system of eddy current field and temperature field, and gives corresponding discrete format with elements as eight nodes, hexahedron equal cell, through calculating eddy - current field to gain the internal heat source that the temperature field needed, to use discrete method to solve the problem of induction - heating part ' s temperature field by axial symmetrical electromagnetic, and then to analyze the characteristic of instantaneous temperature field
本文建立了電磁加熱系統的渦流場和溫度場間接耦合的數學模型，分析了不同頻率下渦流和溫度的分佈情況，並以八節點六面體等參元為例給出了渦流場對應的離散格式，通過計算渦流場獲得溫度場所需要的內熱源強度，加熱部件的溫度場以軸對稱格式進行離散求解，並對瞬態溫度場有限單元法的求解特點進行了分析。The numerical simulation was made on this kind of energy dissipator by using the k - s turbulence model, the full - field distribution of the time - averaged parameter and the turbulence parameter are described in detail, the calculated time - averaged pressure has good agreement with the experimental results, some advice can be provided for the further study and application in this thesis, especially the calculated results can be used to check the lowest time - averaged pressure
本文對洞塞式消能工採用軸對稱的k -模型進行了數值模擬，數值模擬結果詳細地描述了時均流參數和紊動參數的全場分佈，計算所得的壁面時均壓力結果與實驗結果相吻合，獲得了實體試驗難以獲得的流動特徵。可供這種消能工的進一步研究和應用提供參考，特別是可用於檢驗壓力最低點的大小。Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure
試件的整體斷裂為剪切型，但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展，說明局部較高的應力三軸度也會使韌窩型機制得以發展，但是不改變試件整體的剪切型斷裂模式；對韌性斷裂的剪切模式的細觀機理做了一定的探討，並且提出了含裂紋構件剪切型斷裂的宏觀判據：認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向（可簡稱為_ （ pmax ）準則） ，集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷；本文運用金屬韌性斷裂細觀力學在一復合型韌性斷裂方面的研究成果，採用失效評定圖的形式，提出了傾斜裂紋的安全性評定方法的基本框架。
