Crack detection using ultrasonic sensor. Jan 6, 2025 · What Are Ultrasonic Sensors in Crack Detection? Ultrasonic sensors utilize high-frequency sound waves to penetrate materials and detect internal discontinuities, providing a non-invasive method for identifying potential structural weaknesses. In the ultrasonic inspection, the most widely used modes are longitudinal and shear waves for the propagation. Using sonic waves for both transmission and reception, it is possible to measure the crack's width and height as well as its depth in concrete. In this investigation, we introduced an intelligent method that is aimed at developing a crack detection scheme using ultrasonic sensors. In this study, we suggest an affordable and efficient technique for crack detection in concrete buildings utilizing an ultrasonic sensor. May 28, 2025 · Thus, the purpose of this work is to develop a scientific basis for a crack detection method (binary classification), determining the crack depth based on ultrasonic diagnostics data. . By analyzing the reflected waves, the device can detect and characterize the presence of cracks, voids, or other imperfections in the material being tested. Ultrasonic Pulse Velocity (UPV) method is most commonly used to detect the quality of concrete, the position of crack or deepness inside both reinforced and masonry structures. Jun 13, 2022 · Cracks within the concrete can be detected using ultrasonic sensors. Jun 2, 2025 · In order to realize the automatic recognition and classification of cracks with different depths, in this study, several deep convolutional neural networks including AlexNet, ResNet, and DenseNet were employed to identify and classify cracks at different depths and in various materials. hfxs dcyx hhuhiir zavffx zqmn rrw mrua fzklum tnqt glol
