fatigue crack propagation rate

基本解釋

The formula of the fatigue crack propagation rate was directly derived from the fatigue damage criterion.
通過疲勞損傷準則，導(dǎo)出疲勞裂紋穩(wěn)定擴展速率的計算公式。
The results show that the equiaxed and bi-modal microstructures have the similar mechanical properties and fatigue crack propagation rate.
結(jié)果表明：該合金等軸組織和雙態(tài)組織的室溫力學(xué)性能和疲勞裂紋擴展阻抗差別不大；
