specimen thickness effect 中文意思是什麼
specimen thickness effect
解釋
試樣厚度效應-
Studies on the fatigue crack propagation rate ( fcpr ) indicate that load ratio ( r ) has a great effect on the fcpr : the greater load ratio is, the higher the fcpr becomes, and the lower kth shows. compared with load ratio, the thickness of the specimen has a lower effect on the fcpr
對鎂合金的疲勞裂紋擴展特性的研究表明:載荷比r對鎂合金az91 , am50裂紋擴展行為具有很大的影響。 r值越大,裂紋擴展速率越高,疲勞門檻值k _ ( th )越小;試樣厚度t對鎂合金az91 、 am50穩態裂紋擴展速率的影響沒有r值那麼明顯。
