| 英文摘要 | In this paper, a continuous runout method (CRM) is proposed to evaluate the fatigue strength in high cycle and very high cycle fatigue regimes based on the probability and statistics theory. The CRM features the simultaneous testing of multiple samples such that the testing period could be 1/5-1/3 of that by the common up-and-down method for 16 samples. It is validated by the experimental data for G20Mn5QT steel, 40 Cr steel, and Ti-6Al-4V alloy. The predicted lower limits of fatigue strength by CRM are a little more conservative than those by the up-and-down method. |
