  1. The influence of accessorial electrode and electrode distance on the electrodeposition effect was investigated, and three parameters, that is, rate of mass gain, rate of surface coating and rate of crack closure were measured

    摘要就電沉積方法修復混凝土裂縫中輔助電極、電極距離對沉積效果的影響進行了試驗研究，測定了沉積過程中試件質量增加率、表面覆蓋率及裂縫愈合率。
  2. The microscopic plastic deformation of the local crazes cause the change of crack opening loads. therefore, the fatigue crack closure concept could be introduced. a crack closure model of mdyb - 3 pmma were recommended and phenomenologically formulated for positive and negative stress ratios separately, according to the testing results of fatigue crack propagation

    本文討論了有機玻璃疲勞裂紋擴展機理，提出，銀紋的形成是裂紋形成和擴展的基礎，從微觀上解釋了裂紋形成和擴展的原因，並結合金相分析結果，明確提出塑變誘導閉合和粗糙誘導閉合是有機玻璃疲勞裂紋面閉合的兩個主要原因，成功的解析了裂紋面的閉合現象。
  3. ( 3 ) the finite element model, in which the contact between the crack lines is considered, is more accurate than traditional fe model to simulate the crack growth and crack closure

    （ 3 ）建立了考慮裂紋面接觸的有限元模型，較傳統不考慮裂紋面接觸的方法更適于模擬裂紋擴展和裂紋閉合效應。
  4. ( 3 ) both oxide - induced closure and embrittlement of grain boundaries take place for 2 - cr1mo and 2 - cr1mov at high temperature. the change of fatigue crack growth rates with temperature is not so evident as 316land 16mnr

    裂紋表面氧化引進的閉合效應和晶界脆化相對比較均衡，裂紋擴展速率隨著溫度升高的變化沒有鐵素體和奧氏體材料明顯。
  5. Numerical simulation of surface crack propagation considering the crack closure effects and the three - dimensional stress constraints

    考慮閉合效應和三維應力約束的表面裂紋擴展模擬
  6. The phenomenon of crack closure, which is important for the crack growth, is widely existed in the progress of fatigue crack growth in the metal materials

    裂紋閉合現象普遍的存在於金屬材料的疲勞裂紋擴展過程中，對裂紋擴展有著重要的作用。
  7. ( 1 ) oxidation on the crack surface of 16mnr increase with temperature. oxidation mainly takes place on the crack surfaces at 150 ~ 300, which it is serious both on the crack surfaces and in the grain boundaries at 425. oxide - induced closure at 150 ~ 300 results in the drop of crack growth rates

    鐵素體材料16mnr疲勞裂紋表面的氧化隨溫度升高而增大，在150和300時裂紋表面氧化引進的閉合效應要比晶界氧化脆化更明顯，引起在這個溫度范圍內的試驗疲勞裂紋擴展速率下降。
