“…However, there are only a few papers devoted to FE-modelling of phenomena occurring in bolted connections due to damage of fasteners. Rucka et al [23] have applied the wave propagation in diagnostics of the steel bolted bridge parts. Qin and Chu [24] and Qin et al [25] have performed a quasi-static finite element analysis of a typical disc-drum connection used in rotors of large rotating machines, provided that some bolts were removed from the connection model.…”

The aim of the study is the numerical analysis of a bolted connection under the conditions of loss of bearing capacity of some fasteners in this connection. The joined plates in the connection were made of the 3D finite elements, while the fasteners were treated as hybrid models consisting of rigid heads and nuts and flexible beams between them. A model of unilateral contact with friction was used between the joined plates. The bolted connection was first preloaded according to three different tensioning sequences and with a normalised force. After all the bolts were tensioned, the selected bolts were removed, simulating bolt damage under connection loading conditions. The connection was tested for external compressive loads up to 210 kN. The effect of the loosening of the connection on the load in the remaining bolts at the stage of the connection operation was investigated.

“…Since then, rigorous research studies have been conducted for application of these waves in health prognostics of metallic/composite structures [ 27 , 45 , 46 , 47 , 48 ]. Various SHM based studies have been conducted on Lamb waves behavior on metallic and non-metallic structural defects [ 27 , 45 , 47 , 49 ]. These waves have the greater tendency to propagate larger distances (up to 100 m) with little attenuation [ 50 ].…”

Ultrasonic guided wave (UGW) is one of the most commonly used technologies for non-destructive evaluation (NDE) and structural health monitoring (SHM) of structural components. Because of its excellent long-range diagnostic capability, this method is effective in detecting cracks, material loss, and fatigue-based defects in isotropic and anisotropic structures. The shape and orientation of structural defects are critical parameters during the investigation of crack propagation, assessment of damage severity, and prediction of remaining useful life (RUL) of structures. These parameters become even more important in cases where the crack intensity is associated with the safety of men, environment, and material, such as ship’s hull, aero-structures, rail tracks and subsea pipelines. This paper reviews the research literature on UGWs and their application in defect diagnosis and health monitoring of metallic structures. It has been observed that no significant research work has been convened to identify the shape and orientation of defects in plate-like structures. We also propose an experimental research work assisted by numerical simulations to investigate the response of UGWs upon interaction with cracks in different shapes and orientations. A framework for an empirical model may be considered to determine these structural flaws.

“…Pham and Hancock [14], and Pham et al [15] investigated deformations of connections of beams with cold-formed C-sections for different number of bolt rows. There are also only a few papers on modelling the phenomena occurring in bolted connections under the influence of fasteners failure [16][17][18][19]. Therefore, this subject has been taken up in the presented paper.…”

In the paper, experimental studies of an asymmetric preloaded seven-bolted connection are presented. The tightening process of the connection was carried out with a wrench, monitoring the values of the bolt forces with a calibrated strain gauge measuring system. Two methods of bolt tightening were tested: in one and several passes. After all bolts were tightened, the selected bolts were removed, simulating bolt failure under the loading conditions of the connection. The influence of the method and sequence of bolt tightening on the distribution of bolt forces values after the introduction of failure states of some bolts was investigated. The results were statistically processed and presented in the form of graphs showing the distributions of normalised bolt forces values for all the considered failure cases.
