摘要：
The propagation of concrete microcracks has a great influence on the safety and durability of important concrete structures or buildings or Bridges under fatigue load. Traditional nondestructive testing methods are not sensitive to microcracks. In this paper, a method based on broadband excitation nonlinear ultrasonic modulation technology is proposed for detection of concrete propagating microcracks. By means of the extended finite element simulation method, the stress wave generated by ultrasonic excitation is simulated in the concrete model with microcracks. The displacement signal of the concrete model is analyzed by spectral analysis, and the relationship between the length of microcracks propagation and the damage index peak value defined in the nonlinear modulation method is established. Through simulation and experimental detection, the feasibility is studied for broadband excitation nonlinear ultrasonic detection of propagating microcracks under loading. Results show that the real-time dynamic monitoring can be realized for the propagation of concrete microcracks. © 2024 Nanjing University of Aeronautics an Astronautics. All rights reserved.
