  1. The study indicate that the surface form has no effect on kl, but has obvious effect on kll, and will affect the breaking angle and mode ; in finite plate, the boundary condition has effect on the sif and the k is bigger than in infinite plate ; the effect of the distance and the angle between cracks are all have obvious effects on the multiple crack interaction, and the interactions between cracks also have obvious effects on the sif, which can be neglect only when the distance is bigger enough

    研究表明：裂面狀態對k _的大小沒有影響，而對k _的影響卻很大，相同應力條件下，裂面狀態會影響裂紋的開裂角和開裂方式；有限板的邊界對應力強度因子有一定的影響，其k比無限板中的k略大；裂紋間的距離、夾角等因素對裂紋間的干涉效應均有較大影響，裂紋間的干涉效應對應力強度因子的影響非常顯著，只有當裂紋間的距離充分大時，干涉效應才可忽略。
  2. For the laminate which contains a crack, the suggested patch shape is rectangle, the patch thickness is equal to the parent laminate and the patch stacking sequence is the same as the parent laminate. because the length and the width of the patch have the fewer influence on the repair effect, the patch has the least weight on the basis of enough edge distance, end distance and space having been promised

    ?對于含裂紋復合材料層壓板，長方形補片的長度和寬度對修補效果沒有非常明顯的影響，因此在保證連接邊距、間距和端距的條件下，補片大小的選擇應該以節省重量為原則；而當補片的鋪排順序與母板相同、相對厚度為100時能夠獲得比較好的修補效果。
  3. For the nitrogen - implanted samples, the initiation of crack is greatly delayed, and crack spacing interval is small. the samples prepared by pecvd and piii technologies have been investigated using homemade gas permeation tester. the excellent barrier

    而注入件相對沉積件而言，由於沒有明顯的界面層，而表現為改性層裂紋間距小，但沒有完全開裂，具有優良的耐失效性能。
  4. A model based on the concept of the hypothetical fcp element is proposed to give the physical explanations to the existence of fcp threshold and why the fcp rate in near - threshold region coul

    提出了近門檻區內「裂紋擴展基元模型」 ，用於定性地說明何以近門檻區內裂紋擴展速率低於原子間距，進而解釋了裂紋擴展門檻值存在的物理本質。
  5. The cracks extend along the matrix / strengthening - phases interfaces and form the cleavage steps and tear ridges. there appear some very small dimples on the fracture surfaces of the directionally solidified samples, which come from the nb - based solid solution particles in the big plates of the strengthening phases, but no dimples on the fracture surfaces of the as - cast sample. it can be concluded from above results that niobium - niobium silicide based in - situ composites ( rmics ) with a uniformly orientated microstructure can be produced by the ebfzm with high temperature gradient, and their mechanical properties can be increased

    隨著抽拉速率的提高和硅化鈮強化相間距與尺度的減小，材料的室溫拉伸強度和斷裂韌性均有提高， _ b最高可達778 . 4mpa ， k _ （ ic ）達到了46 . 3mpa ? m ~ （ 1 / 2 ） ；試樣的拉伸斷口基本表現為脆性解理斷裂的花樣，裂紋沿基體強化相界面繞過強化相進行擴展，在裂紋擴展方向存在解理臺階，並形成撕裂棱。
  6. Interactions between different cracks and the stress intensity factors for different crack surface forms are calculated, and the effect of the distance and the angle on the stress intensity factor is analyzed

    算例計算了多種情況下裂紋之間的相互作用，分別給出了不同裂面狀態下的應力強度因子，分析了各種情況下裂紋間的距離、夾角等因素對應力強度因子的影響。
  7. Basing on past achievement, we analyzed and gained the damage expression, the craze stress expression in craze zone and the integral equation that the size of craze zone met, all of which changed with time, distance from crack - tip and crack growth ratio

    分析得出本文實驗中銀紋區內損傷、銀紋應力隨時間、距裂尖位置的表達式及銀紋區尺寸所滿足的積分方程。
