Temperature-dependent longitudinal-wave acoustoelastic behavior of concrete

Xiaohan Sang, Tongyu Zhang, Huiling Feng, Feng Qin et autres

The acoustoelastic effect provides a physically grounded basis for evaluating internal stress in structures, but temperature variation can substantially interfere with acoustoelastic stress evaluation in concrete. Nevertheless, the influence of temperature on the acoustoelastic response itself remains insufficiently understood. This study investigates …

Event-triggered passive–active guided wave monitoring for a PZT-embedded smart composite panel

Miyang Wang, Xiaoran Feng, Shengbo Shan, Qingzhao Kong et autres

Abstract Composite structures are vulnerable to impact-induced local anomalies that are often difficult to detect visually, necessitating structural health monitoring (SHM) methods capable of both impact localization and post-impact assessment. This study proposes an event-triggered passive–active SHM framework for a piezoelectric transducers …

Interpretation of subway-induced soil stress-wave signals for detecting coupled cavity-boulder defects

Yang Li, Qingzhao Kong, Yang Xia, Ziye Han et autres

Abstract Underground cavities and isolated stone clusters constitute critical geotechnical hazards that threaten the stability of surface infrastructure and subsurface engineering structures. Conventional geophysical prospecting techniques for detecting subsurface anomalies are often constrained by high operational costs, limited spatial resolution, or low …

The Design and Application of a Digital Portable Acoustic Teaching System

Xiuquan Li, G.C. Tu, Qingzhao Kong, Lin Chen et autres

To address the limitations of traditional acoustic experimental equipment, such as large volume, discrete modules, and complex operation, this paper proposes and implements a set of digital portable acoustic teaching systems. The hardware component is based on an FPGA, enabling a highly …
