“…Analogous conclusions were drawn by Jiang et al [23] and Jikal et al [24] with regard to pitted high strength steel (HSS) wires. For the relevant case of high-strength bolts and bolted details, complying remarks were pointed out by Zampieri et al [25], Lachowiz et al [26], Li et al [27] and Jiang et al [28], which highlighted the influence of increased fretting wear on the fatigue life of corroded specimens, i.e., due to premature crack initiation at worn contact surfaces [25][26][27][28].…”

“…The traditional join method of multi-material structure is bolt connection [4,5]. Mechanical fasteners with bolt-nuts will inevitably encounter problems due to the uneven load distribution and stress concentration, such as loosening [6], reduced clamping force [7], and low fatigue strength [8]. Compared with conventional bolt-nut connection processes, self-piercing riveting (SPR) has the special advantages of no predrilling, fast forming speed, reliable connection, and high fatigue strength [9].…”

The low-velocity impact behaviors of DP590/AA6061 self-piercing riveting (SPR) joints are studied at the impact energies of 5 J, 10 J, 20 J, 30 J, and room temperature (25℃). The lap shear and fatigue tests, and the cross-sectional microscopies of joints are used to assess the mechanical property evolutions of the joints after low-velocity impact. The results show that the absorbed impact energies of SPR joints reach the critical value at an impact energy of 30 J, the exceeded impact energy causes crack failures in the sheets and decreases the interlocking performance of the joints. The static property and the absorbed energy of the SPR joints are reduced by 16% and 36% when the joints are impacted at 30 J, respectively. The low-velocity impacts do not change the failure forms of the joints, but significantly reduce the mechanical interlocking properties of the joints. The fatigue lives of the SPR joints are reduced due to low-velocity impact, and the impacted joints are more sensitive to cyclic loadings.

“…A model for bond stress-slip relationship under repeated loading was proposed through systematic evaluation of the test data. Li et al [17] conducted an experimental study on bolted connection steel plates, studied the combined effect of corrosion and fatigue on the fatigue strength of steel connection plates, and established a model for fatigue strength degradation as a function of corrosion rate. Wang et al [18] studied the fatigue performance of reinforced concrete beams under coupled effects of the cyclic load and corrosive environment, but these tests did not involve the bond deterioration performance between the rebar and concrete.…”

In marine environments, the durability of reinforced concrete structures such as bridges, which suffer from the coupled effects of corrosion and fatigue damage, is significantly reduced. Fatigue loading can result in severe deterioration of the bonds between reinforcing steel bars and the surrounding concrete, particularly when reinforcing bars are corroded. Uniaxial tension testing was conducted under static loading and fatigue loading conditions to investigate the bonding characteristics between corroded reinforcing bars and concrete. An electrolyte corrosion technique was used to accelerate steel corrosion. The results show that the bond strength was reduced under fatigue loading, although the concrete did not crack. Therefore, fatigue loading has negative effects on the bond strength between corroded steel bars and concrete. The effects of corrosion cracking on bond strength become more pronounced after corrosion cracking appears along the main reinforcing bars. When the average width of cracking along main reinforcing bars exceeds 3 mm, the bonding properties deteriorate rapidly based on the effects of corrosion cracking, whereas fatigue loading exhibits no additional effects on bond strength.
