First, vibration fatigue tests were conducted on 2024‐O aluminum alloy components under four different stress levels. To address the issue of local damage characteristics under vibration fatigue, a scan window to achieve the local phase velocities within a small local region was employed, and then, the local stiffness can be calculated. By tracking the residual stiffness of the weakest region, the local damage factor was calculated. A unified model with normalized periods at different stress levels was carried out to predict the evolutionary trend. This approach offers a more efficient alternative to estimate local fatigue damage and residual life through the monitoring of local stiffness during maintenance. 10.1111/ffe.14413 http://onlinelibrary.wiley.com/termsAndConditions#vor |
