摘要：
The fatigue and dwell-fatigue crack growth rate of a new titanium alloy under complex load spectrum was investigated by experimental method while the influence of upper peak load dwell time and lower peak dwell time on the dwell-fatigue crack growth behavior was analyzed. Based on the fracture mechanics, a new dwell-fatigue crack growth rate prediction model was established for the new titanium alloy, and was verified by experimental method. The results show that the crack growth behavior of the new titanium alloy material is sensitive to the upper and lower peak dwell time. The crack growth rate increases with the increase of the upper and lower peak dwell time, but the trend of increasing gradually decreases, indicating there exists a certain saturation value for the influence of dwell time on the crack growth rate of the new titanium alloy. A new dwell-fatigue crack growth rate prediction model for titanium alloys was proposed. The dwell-fatigue crack growth rates under complex load spectrum were predicted. The prediction results are in good agreement with the experimental ones. © 2023 China Ship Scientific Research Center. All rights reserved.
