  1. The crack - growth increment of crack - line is computed by paris formula followed by fitting using three - time b - spline function

    根據以上思想方法，編寫了具有較高的計算效率和精度的數值模擬程序。
  2. Secondly, the influences of the random parameters on fatigue propagation are discussed in the fatigue propagation paris formula

    其次，論述了疲勞裂紋擴展公式中各隨機參數對疲勞擴展速率的影響。
  3. In spite of that, the cracks propagate stably in specimens for all types of tests. thus the paris formula can be used to describe the fatigue crack propagation, and the values of fatigue fracture parameters in the paris formula are regressed by using the results of fatigue damage and stress intensity factors computation

    盡管如此，不論對哪種疲勞試驗，其試件疲勞裂縫擴展主要表現為穩定擴展，可以運用paris公式描述疲勞裂紋擴展階段，並利用疲勞損傷數值模擬計算結果和裂縫擴展過程中的應力強度因子回歸了疲勞裂縫擴展速率公式中的疲勞斷裂參數。
  4. In the existing literature, the material coefficients are simply considered as constants. yet the material coefficients c and n in paris formula are randomized in this study. using the least square method, the statistical correlation between c and n is obtained through the numerical value collocation

    將以往文獻中通常看作是確定性的材料系數隨機化，通過對大量數據進行數理統計的分析，將疲勞裂紋擴展速率paris公式中材料系數c和n視為隨機變量，採用最小二乘法對c和n進行數值擬合，從而得到二者的統計相關性表達式。
  5. We conduct fatigue crack growth experiment with four kinds of materials through the method, and get complete date of four kinds of materials " fatigue crack growth at first time. and also gain the laws of these four kinds of materials " at between 25 and 550 separately, that is the coefficient and exponent of paris ' s formula. meanwhile finding out the laws of fatigue crack growth of these four kinds of materials with the temperature changing

    採用上述試驗方法對四種材料高溫疲勞裂紋擴展行為進行試驗研究，首次獲得了16mnr 、 21 / 4cr1mo 、 21 / 4cr1mov和316l四種材料較為完整的高溫疲勞裂紋擴展數據，並得到四種材料在25 550溫度條件下的疲勞裂紋擴展規律表達式（即所對應的paris公式的系數和指數） ，找到了這些材料隨溫度變化的疲勞裂紋擴展規律。
  6. By an example, each parameters are randomized in the paris formula, and the propagation life of fatigue of the structure is prognosticated on the presented reliability

    通過算例，將疲勞裂紋擴展速率公式中的各個參量全部隨機化，並預測構件在給定可靠度下的疲勞裂紋擴展壽命。
