Baseline-free absolute strain estimation for cylindrical structures
Engineering Structures(2023)
摘要
•Baseline-free absolute strain estimation technique is developed.•Absolute strain of in-service cylindrical structures was estimated.•Acoustoelastic effect of ultrasonic guided waves was employed.•Proposed method does not need calibration tests or baseline data.•Developed technique can be applied to in-service cylindrical structures.
