crack-growth rate

基本解釋

If the failure is defined as the final fracture of a component, then both S-N curves and crack growth rate curves reflect the fundamental material behavior under fatigue loading.
如果都把一個(gè)構(gòu)件的最終斷裂作為疲勞破壞的定義，則S -N曲線和裂紋擴(kuò)展率曲線均是反映金屬在疲勞載荷作用下的基本材料特性。
Furthermore, the crack initiation period and crack-growth rate are computed according to the principles of fatigue fracture mechanics, and the obtained results accord with real instance.
此后，采用斷裂力學(xué)理論研究了出口邊水蝕缺口處的裂紋萌生期與擴(kuò)展的增長(zhǎng)率，計(jì)算結(jié)果與實(shí)際裂紋發(fā)展情況較為符合。
Based on the features of the three-dimensional crack, an experimental method was presented to measure the near-threshold fatigue crack growth rate and threshold of the corner crack at a hole.
基于三維裂紋特征，本文提出了一種測(cè)量孔邊角裂紋近門檻區(qū)疲勞裂紋擴(kuò)展速率及門檻值的實(shí)驗(yàn)方法。
