In this work, we present a quantitative and qualitative analysis of the dynamic response of
ball bearings dependent on radial internal clearance. We measured the vibrations of a …

This article presents the results of a recurrence analysis conducted on the milling of GFRP
material. The novelty lies in applying variable milling parameters to assess the detectability …

Monitoring the looseness degree of multi-bolt connections is significant for ensuring the
safety of steel structures. Among existing structural health monitoring techniques, the active …

This work experimentally addresses damage calibration of an unmanned aerial vehicle in
operational condition. A wide range of damage level and types are simulated and controlled …

Civil engineering structures usually exhibit time-varying characteristics under operational
conditions due to changes in environment and loads. The identification of instantaneous …

The piezoelectric active sensing method has been proven to be an effective, nondestructive
approach for bolt looseness monitoring. The conventional damage index relies on the …

Excessive accumulation of irreversible plastic strain in ratcheting poses a highly urgent need
in early-stage damage evaluation. A strategy integrating critically refracted longitudinal (L …

The collection and analysis of acoustic emission (AE) from weld circumferential cracks are
crucial for ensuring pipeline safety. However, the unclear propagation characteristics and …

As a safe and reliable connection, bolted connection is widely used in various structural
systems. Monitoring the bolted connection is beneficial to ensure the safety of the whole …

Valve stiction is a common and persistent fault of industrial loops in process control. The
