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 …

Fatigue reliability (FR) evaluation is crucial for extending the service life and improving the
reliability of automotive engines. This study proposed a general framework for assessing …

The torque-tension relationship of threaded fasteners affects almost all engineering
disciplines. Tribological processes at fastener interfaces manifest as the system's friction …

A method of hyperstatic mechanics analysis of guideway assembly and motion errors
prediction under thread friction coefficient uncertainties is proposed. Based on the …

This study investigates the effect of shot-peening on the bearing friction coefficient of
42CrMoV grade 14.9 screws. An experimental campaign was conducted on a tribological …

The clamping force of the bolted joint is a key factor in maintaining its service performance.
However, when the torque wrench is removed after tightening, there will always be a certain …

Due to its strength advantage, high strength bolts are able to provide larger clamping force.
However, the changing behavior of friction coefficient during repeated tightening will …

Bolted joints are one of the most widely used forms of connection. As the weak link, its
contact stress directly influences the mechanical properties of a structure. In this work …

In general, bolted connections are exposed to vibrations or repeated over-loads that could
lead to self-loosening due to loss of preload. Pre-tensioned bolts in ring flanges are critical …

Fractal parameters (FP) significantly influence contact mechanics characteristics, such as
contact stiffness, friction and wear. The existing methods liking the power spectral density …
