  1. Dislocation distribution function of mode crack under action of superimpose and impact loads

    型裂紋的位錯分佈函數
  2. Applying perturbation technique, the image force on dislocation is obtained when dislocation located arbitrary point either outside or inside inhomogeneity, however, a number of previous related investigations on above problems only calculated the interactive dislocation force as the dislocation lies on the x - axis. the variation of screw dislocation forces for correlative material parameters and different radians of crack or rigid line is discussed particularly

    針對以往大多數相關文獻~ （ [ 7 ] - [ 16 ] ）只求出了位錯在x軸上時位錯力表達式，本文應用擾動技術，導出了位錯在基體或夾雜中任意點的位錯力公式；並討論了位錯力隨材料相關參數，裂紋或剛性線弧度的變化規律。
  3. The influence of crack geometrical dimension and materials elastic constants on edge dislocation force is evaluated and discussed when dislocation is located in matrix

    在壓電材料中，由於電彈耦合效應，軟夾雜也可能排斥位錯。
  4. Many dislocations were emitted from the grainboundary in the front of crack and were driven out of grain boundary area, leaving dislocation free zone in the front of grainboundary. a concept of grainboundary dislocation free zone is proposed. the deformation in the front of crack tip in magnesium was single slip, which resulted in the thinning in the area of crack tip

    首次發現裂尖前方晶界對裂尖發射的位錯有排斥作用，裂尖前方的晶界可以向晶界兩側晶粒發射位錯，位錯從晶界發出后迅速離開晶界向前運動，形成晶界無位錯區，首次提出晶界無位錯區的概念。
  5. It was found that many dislocations were emitted from the crack tip during the early stage of crack propagation and were driven out of the crack tip area, and them piled up inversely. a closed dislocation free zone ( dfz ) was formed between the crack tip and the pile - up dislocations. keeping displacement constant, the dislocations were still emitted from the crack tip for a while

    本文首先系統地研究了工業純金屬（ fe ， al ， ti和mg ）斷裂的微觀過程，發現所研究的工業純金屬斷裂過程裂尖均首先發射位錯，並離開裂尖向前運動、在裂尖留下無位錯區，位錯反塞積在五位錯區的端部，反塞積位錯群一般呈封閉狀包圍無位錯區。
  6. Keeping displacement constant, the length of dfz decreased. the less the lattice resistance is, the longer the dfz is. during the crack propagation, the pile - up dislocations may move forward in the previous direction or in another direction which caused shape of dfz changed. the dislocations emitted from the crack tip might pile up in the dfz and can be served as dislocation source in the successive loading

    在裂紋擴展過程，反塞積位錯群發生變化，可以沿原來方向繼續向前運動，也可能改變運動方向使無位錯區的形狀發生變化，后來發射出的位錯可以在原五位錯區中塞積，並可作為位錯源在後續的加載中發射位錯。
  7. Dislocation distribution function of the edges of an axially symmetric crack subjected to unit - step loads

    軸對稱裂紋表面受階躍載荷的位錯分佈函數
  8. It is shown that the interfacial crack has a significant effect on the equilibrium position of the edge dislocation near circular interface. the results also exhibit a strong dependency different between the shear modulus and poisson ' s ratios of the matrix and the inclusion

    刃型位錯與含界面裂紋的夾雜干涉效應表明：當位錯接近界面時，裂紋對位錯平衡位置有很大的影響；平衡位置對兩種材料的彈性性質也有很大依賴性。
  9. The interaction between piezoelectric screw dislocation and circular crack under remote uniform heat flux

    均勻熱流場中螺型位錯與圓弧裂紋的相互作用
  10. As a result, analysis and discussion show that the influence of interfacial crack or rigid line inclusion on the interaction between screw dislocation and inhomogeneity is significant

    分析結果表明，界面裂紋和剛性線夾雜對螺型位錯與夾雜的干涉作用具有強烈的擾動效應。
  11. The interaction effects between circular interfacial cracks or rigid line inclusions and a screw dislocation located either outside or inside inhomogeneity under antiplane shear, the electroelastic interaction between a piezoelectric screw dislocation located either outside or inside inhomogeneity and circular interfacial cracks and rigid lines under longitudinal mechanical and inplane electrical loads in linear piezoelectric materials and the elastic interaction between an edge dislocation located either outside or inside inhomogeneity and interfacial crack along a circular inhomogeneity are dealt with in this paper

    本文首次對位錯與圓形彈性夾雜界面典型缺陷的力、電干涉進行研究，解決了無窮遠反平面剪切作用下螺型位錯與含界面裂紋或界面剛性線圓形夾雜的彈性干涉問題；無窮遠縱向剪切和面內電場共同作用下壓電螺型位錯與含界面裂紋或界面剛性線圓形壓電夾雜的力電耦合效應問題：刃型位錯與含界面裂紋圓形彈性夾雜的干涉問題。
