title = "Ultrasonic Measurement Method of Bolt Axial Stress Based on Nonlinear Acoustics",
abstract = "An ultrasonic stress measurement method based on nonlinear acoustics was proposed to address the issues with current ultrasonic measurement technology for bolt axial stress, such as low accuracy and complex operation. The method involves analyzing the propagation of ultrasonic waves in bolts and using obliquely polarized single-vibration element transverse and longitudinal wave transducers for measuring axial stress. By applying nonlinear acoustic theory and elastic mechanics theory, an expression for calculating bolt axial stress through the transverse and longitudinal wave sound time ratio was derived. A bolt axial stress ultrasonic measurement test platform was constructed to conduct calibration and axial stress measurement experiments on bolt specimens. The results indicate that this method offers high measurement accuracy and a straightforward measurement process.",
