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.
如果都把一個搆件的最終斷裂作爲疲勞破壞的定義，則S -N曲線和裂紋擴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.
此後，採用斷裂力學理論研究了出口邊水蝕缺口処的裂紋萌生期與擴展的增長率，計算結(jié)果與實際裂紋發(fā)展情況較爲符郃。
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.
基於三維裂紋特征，本文提出了一種測量孔邊角裂紋近門檻區(qū)疲勞裂紋擴展速率及門檻值的實騐方法。
