Loosening of threaded fasteners can cause preload decline, induce bolt fatigue fracture, and
severely compromise the reliability of mechanical products. Loosening detection is an …

Pre-stressed bolted joints are widely used in civil structures and industries. The tightening
force of a bolt is crucial to the reliability of the joint connection. Loosening or over-tightening …

In this study, a quasi-autonomous vision-based method is newly proposed for detecting
loosened bolts in critical connections. The main idea of the approach is to estimate the …

It is crucial to monitor the real-time strength development of early-age concrete, which is
related to the structure safety and construction efficiency of concrete. This paper proposed a …

In the electromechanical impedance-based technique, the selection of proper impedance
features and frequency bands has played a significant role in enhancing the results of …

This study presents a novel autonomous vision-based bolt-looseness detection method for
splice bolted connections. The method is sequentially designed with a Faster regional …

Traditional impedance-based bolt-looseness monitoring approaches using hand-crafted
impedance features can lead to difficulties in quantitative damage severity estimation. In this …

Earlier identification of bolt loosening is crucial to maintain structural integrity and prevent
system‐level collapse. In this study, a novel drone‐based 3D vision methodology has been …

Corrosion induced material loss in metallic structures is a widespread and urgent problem
across multiple industries. In this paper, a novel corrosion monitoring method is proposed …

Bolted joints are fundamental building blocks and have been widely used to hold multiple
structural components together, while their looseness may lead to costly disasters in …
