Loosening of threaded fasteners is a key failure mode, which is mainly caused by the
slippage and friction behaviors on the thread and bearing surfaces, and will affect the …

Many contact-sensor-based methods for structural damage detection have been developed.
However, these methods have difficulty compensating for environmental effects, such as …

The use of bolted flange connections in the offshore wind industry has steeply risen in the
last few years. This trend is because of failings observed in other modes of joints such as …

The rotors of large rotating machinery involve multiple stages of disks supported by drums
and shafts, where bolted joints are commonly employed to connect the adjacent disks and …

Loosening tests of bolted joints are carried out under various preloads and excitation
amplitudes. Three coatings are utilized to treat bolts, and their effects on the anti-loosening …

The presence of service torque, which is generated after tightening, directly affects the
mechanical properties of bolted joint. In this work, the mechanical behavior of bolted joints …

In this paper, a vibration testing and health monitoring system based on an impulse
response excited by laser ablation is proposed to detect bolted joint loosening. A high power …

Bolts are widely applied to the connections of structural components. Under the actions of
alternative forces induced by the external loads, the bolts are commonly inevitable to be …

The self-loosening failure of bolt connection will bring a series of problems. Sakai first
proposed the self-loosening theory of fixed nut and free bolt head under rotational vibration …

It has been widely observed that fasteners turn loose when subjected to dynamic loads in
the form of shock, vibration or transverse cyclic loading. This reduces the preload force of …
