crack growth rate curve

基本解釋

A small sample method for testing fatigue crack growth rate curve of steel was presented in this paper using a formula of two-dimensional one-side tolerance factor.
應用二維單側容限系數(shù)公式，提出了一種測定金屬材料疲勞裂紋擴展速率的小樣本方法。
One is the cumulative fatigue damage(CFD) theory based mainly on S-N (or ε-N) curves and the other is the fatigue crack propagation (FCP) theory based on the crack growth rate curve.
提出了一種確定海洋平臺鋼裂紋擴展曲線的快速方法，該方法可以綜合利用以往的經(jīng)驗數(shù)據(jù)和當前試驗數(shù)據(jù)確定表面疲勞裂紋擴展速率曲線。
The results show that the rate of the growth of each point on the surface crack is connected with the place of crack and the structure of nozzle, and its steady shape is some of complex curve.
結果表明：表面裂紋各點的擴展速度與其所處的位置和容器接管的幾何參數(shù)有關，且其擴展平衡狀態(tài)為一不規(guī)則形狀。
