用裂紋單元分析雙壓電材料界面力電耦合奇異場Finally, an energy approach is combined with the fem in the simulation of the crack propagation along the fiber / matrix interface in a pull out process. the simulated results are in nice conformity with experimental results. the second part of the research deals with the characterization of the failure process in the fragmentation tests, which is one of the most frequently used test methods in studying thermal mechanical properties of fiber / matrix interfaces
在這一部分工作的最後,採用能量法與有限元法結合起來,模擬纖維抽拔試驗中裂紋的擴展:針對以往研究工作中的不足之處,在模擬中使用能量釋放率,在表徵界面破壞時,所使用的應力強度因子考慮了纖維和基體兩種材料的不同屬性,並考慮裂紋尖端的單元奇異性,來研究裂紋長度和溫度對裂紋擴展的影響。The numerical results show mat the fem models applied in this paper are correct, and the hybrid element method is effective in approving calculation efficiency
雜交元計算結果表明對于求解應力奇異性問題,構造合適的雜交單元可以有效的提高計算效率。4. because there are sub - elements in a member with the introduction of inner joints, when tile spatial stifmess matrix of main joints of a member is made, there are some cases of solving the double nonlinear equations, negative stifmesses, and singular stiffness matrices in process of iterating
4 、由於引入了內結點,構件存在子單元,在形成主節點的構件空間單元剛度矩陣時,存在雙重非線性方程求解,迭代過程中負剛度和剛度矩陣奇異問題。We extend this method to the problem of a domain which boundary is an open arc or an open segment. in this paper, we simulate the singularity of solution in extreme point of open arc or open segment by singular element
本文還把此方法推廣到求解區域邊界是直線段或者開弧段的情況,採用引入奇異邊界單元的方法來模擬解在開邊界端點附近的奇異性。Firstly, after depicting the singularity of stress field at the top of crack, the finite element method to calculate stress intensity factor of plain fracture problems is founded
首先,對反射裂縫尖端應力場的奇異性進行了描述,建立了平面斷裂問題應力強度因子的有限單元解。The characteristic of this model is : a new interface edge singular element model is derived based on the numerical fundamental solutions obtained from the finite element eigensolutions method
該模型的獨特之處在於:基於有限元特徵法得到的奇異性場數值特徵解建立了一種新型界面端奇異單元。It is based on a point - value multi - resolution analysis that is used to detect regions with singularities ( e. g. shocks ), instead of a cell - average value multi - resolution analysis
在點值多分辨分析的基礎上,我們利用其來探測具有奇異性的區域范圍(比如包括激波的區域) ,而不是用單元平均值的多分辨分析。分享友人
