“…For the same value of w / t , an increase in pressure also reduces the energy dissipation. It should be noted that the results reported in this article are in agreement with the experimental finding reported by Eriten et al 19 in terms of both the evolution of the energy dissipation as a function of applied maximum remote load and the effect of bolt pre-load. Although a direct comparison with existing experimental data is outside the scope of the present contribution, it is envisaged that an extension of the approach to incorporate three-dimensional effects will enable performing fast quantitative analyses of energy dissipation in lap joints.…”

In this article, we consider the interfacial characteristics of a lap joint formed using friction grip bolts. The joints consist of two elastically similar laps pressed in contact by a constant normal force and subjected to oscillatory bulk load at the free end of the laps. It is found that application of the normal load causes the contact area to jump to a characteristic length and the points where separation occurs are fixed. Bulk load applied at the free ends causes a smooth change in the size of contact and the development of the slip zones. The trends of energy dissipation with extent of contact and magnitude of tension and compression force, at various friction coefficients, have been found.

“…Comparisons of the identified Iwan model and experimental data are plotted in Figure 12. Parameter χ varies from À0.7 to À0.05, which also agrees with the observations by Ames et al (2009) and Eriten et al (2011aEriten et al ( , 2011b. It is shown that the four-parameter Iwan model can well reproduce joint damping properties with different contact roughness and bolt arrangements.…”

“…It showed that tangential contact stiffness during micro-slip stage tended to be linear. Initiation of macro-slip was observed at a length scale of 10 À6 m. Hysteresis loops of aluminum and steel joints under different preloads were obtained by Eriten et al (2011aEriten et al ( , 2011bEriten et al ( , 2012 from their quasi-static and dynamic experiments. It is indicated that aluminum joints generally dissipated more energy than steel joints.…”

A modified and simplified oscillator device is designed and manufactured to investigate the effects of contact roughness and bolt arrangements on energy dissipation caused by joint damping. Three types of surface roughness and five different bolt arrangements are discussed. Identification of Iwan model based on experimental data is carried out. It is indicated that rough surface dissipates more energy than smooth one. Specimens with more bolts dissipate relatively more energy. When bolt number is consistent, the series type dissipates more energy than the parallel type. Experimental data show a good stability and accuracy of the proposed oscillator device. The identified Iwan model provides a good conformity with the reconstructed hysteresis loop. The four-parameter Iwan model can well describe the damping property of joints with different surface roughness and bolt arrangements.

Bolted joints play a more and more important role in the structure with lighter weight and heavier load. This paper aims to provide an overview of different experimental approaches for the dynamic behavior of structures in the presence of bolted joints, especially the energy dissipation or damping at frictional interfaces. The comprehension of energy dissipation mechanisms due to friction is provided first, while the key parameters and the measurement techniques, such as the excitation force, the preload of the bolt, or the pressure at the interfaces, are briefly introduced. Secondly, the round-robin systems aim to measure the hysteresis parameters of the frictional joints under tangential loads are reviewed, summarizing the basic theory and the strategies to apply the excitation force or acquire the response in different testing systems. Followed by parameter identification strategies for bolted structures, the test rigs with one or more simplified bolted joints are summarized to give an insight into the understanding of typical characteristics of bolted structures, which are affected by the presence of friction. More complex test rigs hosting real-like or actual engineering structures with bolted lap or flange joints are also introduced to show the identification process of the dynamic characteristics of bolted connections employed in specific applications. Based on the review paper, researchers can get the basic knowledge about the experimental systems of the bolted structures, especially several classical round robin systems, such as the Gaul resonator and widely used Brake-Reuß beam system. Readers can take advantage of this background for more creative and effective future studies, make more progress on the study of assembled structures and understand the influence of bolting frictional connections on the dynamic response better.
