Sequential quantification strategy of delamination in composite laminate via collaborative active and passive monitoring

Xuyun Ding et al.

Summary: A sequential quantification method for delamination in thin-walled fiber-reinforced composite laminate is proposed in this paper, which combines active piezoelectric sensors with passive strain sensors to accurately estimate the center and boundary points of delamination and identify the depth of delamination through Bayesian posterior inference. The feasibility, accuracy, and efficiency of the proposed methodology are demonstrated through numerical and experimental cases, with detailed discussions on robustness.

Fatigue crack detection under the vibration condition based on ultrasonic guided waves

Yanping Zhu et al.

Summary: This article explores the detection of fatigue cracks in vibration condition caused by operation using ultrasonic guided waves, proposing a detection method based on the difference index and the sequence curve of difference index between different states of crack. Experimental results show that loads from 0 to 24 MPa have minimal effect on ultrasonic guided waves, and the method based on difference index value and sequence of difference index is reliable for detecting fatigue cracks in structures under vibration conditions.

Numerical and experimental flight verifications of a calibration matrix approach for load monitoring and temperature reconstruction and compensation

Luca Colombo et al.

Summary: This study proposes a method for recovering the full strain and displacement fields in a structure using a Calibration Matrix approach, leveraging on the thermal variation among unknown parameters. The method exploits least-squares minimization to reconstruct load and temperature, automatically compensating for thermal effects on strain measurements. The method is tested with a UAV undergoing different operational maneuvers, showing robustness in reconstructing strain and displacement fields due to aerodynamic loads.
