“…In the finite element model, the upper sheet was 1.5mm 5052 aluminum alloy sheet and the lower sheet was 1mm Q235 steel sheet. Their basic mechanical properties are shown in Table 1 [22][23][24]. The quality of the clinching joints depends on the flow of the sheet metal.…”

Aiming at the problems of low strength and unsatisfactory connection quality of plastic clinching of heterogeneous lightweight materials for the cars body, the Q235 steel sheets, and 5052 aluminum alloy sheets were taken as the research objects, and the inclined wall die for plastic clinching was designed based on the deformation and flow characteristics of sheets in the plastic clinching process. The elastic-plastic finite element numerical simulation and experimental research were used to analyze the plastic clinching process of the inclined wall die, and the failure mode and mechanism of the clinching joints in the shear and peel experiment were deeply studied. The results show that the inclined wall die can effectively increase the interlock value of the joints and reduce the maximum joining force during the clinching process under the condition of ensuring the neck thickness of the joints. When the inclined wall angle α increases from 90° to 100°, the interlock value increases by 38.9%, and the maximum joining force decreases by 8.3%. The influence of inclined wall structure on joint quality can be divided into extrusion stage, radial inflow stage, and stability stage. The comparison between the clinching experiment and the finite element results shows that the two results are in good agreement, which proves that the finite element model of plastic clinching of inclined wall die has a high degree of credibility, and verifies the feasibility of practical application of inclined wall die. Finally, under shear and peel loads, the main failure mode of the joints is separation failure.

“…Many studies on the hybrid connection between light alloy and fiber-reinforced materials have been conducted by many scholars. SPR [10,28,29], MC [30][31][32][33], and other processes [34][35][36] are used to join hybrid structures composed of light metal materials and fiber-reinforced composite materials. In some work on the connection of composite structures by SPR [10,28,29], a numerical simulation model of the SPR process between CFRP and aluminium alloy plates was established [28].…”

“…According to its results, this method is beneficial to reduce the damage of CFRP sheets, contributing to the strength of the hybrid structure. On the other hand, Lin et al [31,32] used the MC technique to join the composite structure between Al5052-H32 and thermoplastic CFRP. The process conditions were also determined, verifying the practicality of the MC technique.…”

With the wide application of lightweight materials, the metal–polymer multilayer structure has become a research focus owing to the advantages of lower weight and higher vibration damping. In the current work, the mechanical clinching process of the metal–polymer multilayer structure between Al5052-H32 and polyoxymethylene was investigated. The effect of diverse plate configurations and different test specimen forms on the mechanical characteristics was analysed in terms of geometric parameters, static strength, failure modes and energy absorption. The results showed that the metal–polymer multilayer structure could be successfully connected utilizing the mechanical clinching process. The cross-tension load and lap-shear load of the joint were greatly affected by the plate configuration as well as the test specimen form.

“…Carbon-fiber-reinforced plastic (CFRP) can be used as an excellent lightweight replacement for steel in mechanical industries [ 1 , 2 , 3 , 4 , 5 ] due to its outstanding specific strength characteristics [ 6 , 7 , 8 , 9 , 10 , 11 ], as well as its sound damping characteristics [ 12 , 13 , 14 , 15 , 16 , 17 ]. The dynamic response of a CFRP structure varies with the changes in structural stiffness with respect to the direction of the carbon fiber; hence, CFRP is anisotropic in nature due to the different orientations of the carbon fiber [ 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

The dynamic properties of carbon-fiber-reinforced plastic (CFRP) can be efficiently estimated through a modal damping coefficient and a resonance frequency, and the modal parameters can be calculated using a frequency response function (FRF). The modal parameters used in an CFRP FRF are influenced by the carbon fiber direction, temperature, and spectral loading pattern, as well as the operating conditions. In this study, three parameters—temperature, spectral loading pattern, and carbon fiber direction—were selected as the influential factors for CFRP dynamics, and the sensitivity index formulation was derived from the parameter-dependent FRF of the CFRP structure. The derivatives of the parameter-dependent FRF over the three considered parameters were calculated from the measured modal parameters, and the dynamic sensitivity of the CFRP specimens was explored from the sensitivity index results for five different directional CFRP specimens. The acceleration response of a simple CFRP specimen was obtained via a uniaxial excitation test at temperatures ranging from −8 to 105 °C for the following two spectral loading cases: harmonic and random.
