Contact and friction are closely related as friction cannot happen without contact. They are
widely used in mechanical engineering, traffic, and other fields. The real contact surface is …

Threaded fasteners are vastly used in the industry due to ease of mounting and dismounting
and flexibility of design. Nonetheless, several researchers indicate that most failures …

Fretting wear is a material damage in contact surfaces due to micro relative displacement
between two bodies. It causes some unexpected results, such as loosening of fasteners or …

This paper investigates the effects of fretting wear on frictional contacts. A high frequency
friction rig is used to measure the evolution of hysteresis loops, friction coefficient and …

The tangential contact stiffness is an important parameter used in non-linear dynamic
analyses of jointed structures since it can strongly affect the prediction of resonance …

A finite-element model of the interaction of an elastic–plastic asperity junction based on
cylindrical or spherical asperities is used to predict sliding friction coefficients. The modelling …

This paper focuses on an experimental investigation of the mechanical behavior of bolted
joints. A new test apparatus to measure friction hysteresis was designed to provide a reliable …

The accurate description of the dynamics of dry-joint masonry structures strongly relies on
the characterisation of the interaction at the units' interfaces. Several experimental …

The present work aims to expand the knowledge of the behaviour of masonry corners, which
are capital to obtain an integral seismic response in masonry buildings. In particular, the …

Bolted joints may suffer from fretting damage which can significantly decrease fatigue life. A
testing arrangement was developed to study the effect of different operating and design …
