  1. Safety of structures is a common and important problem in the mechanical engineering. recent years there is a trend of developing unified theory of fatigue and fracture to describe the life - cycle damage behaviour of structures. researches on safety guarantee are going toward multi - method synthesis, system micromation, network availability and life - cycle information management

    結構的安全性一直是工程中普遍關心的重要問題，結構強度學逐漸發展到疲勞斷裂統一理論，結構安全保障手段已向多方法、微小化、網路化和全壽命在線保障與監測發展，建立全壽命安全保障系統，涉及材料、機械、力學、電子等學科的交叉融合。
  2. It follows that the fracture behaviour and the impact toughness and magnetic properties, especially the coercivity, were dramaticly different according to the ways elements addition

    結果表明，不同合金元素或不同添加方式，對磁體斷裂方式、沖擊韌性及磁性能（特別是矯頑力）有不同的影響。
  3. The impact toughness of the magnets with 0. 05 % ag was 70 % higher than that of commercial n35 magnets without magnetic properties deterioration. and there was no visible changes to fracture behaviour of these magnets

    添加0 . 05 % ag磁體沖擊韌性較普通商業n35磁體提高70 % ，同時磁性能幾乎沒有降低，並且該成分磁體斷裂方式沒有明顯改變。
  4. The impact toughness of the magnets could be improve with appropriate alloying elements addition during ball milling while there was no visible changes to the fracture behaviour, and the coercivity of magnets with al and ti was significantly enhanced

    晶間單獨或復合添加適量合金元素對磁體沖擊韌性均有一定提高作用，但對斷裂模式沒有明顯影響，復合添加ti 、 al能顯著提高磁體矯頑力。
  5. The impact toughness of the magnets with al and ti during melting could be prominently improve, and the fracture behaviour of the magnets was visibly changed, but the coercivity of magnets depended on the proportion of al and ti

    熔煉復合添加ti 、 al明顯提高磁體沖擊韌性，並且對磁體斷裂模式影響較大，矯頑力隨ti 、 al的添加比例出現較大波動。熔煉合金化的nd15 . 5fe76 . 5al1ti0 . 5b6 . 5磁體沖擊韌性較商業n35磁體提高了51 . 8 % ，磁性能略有下降。
  6. A finite element analysis ( fea ) was eventually conducted, using mori - tanaka model and j - integral, to further explain the toughening mechanisms and fracture behaviour of the particle interleaved composites. the aim of the analysis was to examine the influence of the particle concentration and size, and the interaction between the particle and the crack tip. fea results indicate that interlayer zones can effectively lower j - integral and stress around the crack tip, and the high stress distribution in the region close to the interface can be the driving force for interfacial failure

    本文的最後還藉助于有限元方法對層間增韌復合材料進行了宏觀和細觀斷裂韌性分析，基於mori - tanaka等效夾雜理論，計算了顆粒含量和尺寸對j積分的影響，有限元分析的結果同樣表明層間增韌可以有效的降低裂紋尖端應力水平，並暗示界面是可能存在的失效原因，所進行的數值分析起到了進一步支持和解釋增韌機理的作用。
