Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

Bolted flange joints are widely used in pressure vessels and pi**. With the increase in
installation of nuclear power plants, chemical industries and oil and gas transportation …

The aim of this study is to provide an experimental methodology useful to determine the
friction coefficients in bolted joints and, therefore, to relate precisely the tightening torque to …

Threaded fasteners are one of the most commonly used connection methods for mechanical
structures. Its primary function is to generate appropriate clam** forces and fasten the …

A method has been developed to quantify the bearing surface friction coefficient in bolted
joints based on the mechanics of the tightening process. By measuring the surface …

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

In this research, three types of lubricants are investigated for their effects on the friction and
torque-tension relationships in threaded fastener applications. Investigated lubricants …

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 …

In recent years, the need for lighter vehicles led to the widespread of lightweight alloys, such
as titanium, also in the field of threaded fasteners. Unluckily, the replacement of steel bolts …

An experimental study is presented in order to determine the clamp load loss due to elastic
interaction and gasket creep relaxation in bolted joints. Studied parameters include the …
