“…The constitutive model must be calibrated by comparing experimental and simulation results to reveal the mechanism of the clinching process. The previous articles [90][91][92][93][94][95] mainly analysed and predicted the distribution of stress, strain and other process parameters on the clinched joint for the different clinching technologies. Some studies deal with the modelling of the clinching process without considering ductile damage evolution.…”

The clinching technology attracted increasing attention in recent years, but its application might be restricted due to the growing employment of materials that are difficult to join and hybrid structures involving different mechanical performance materials. Traditional clinching technology has limitations of strain rate sensitivity, ductility and damage fracture when applied to materials with high strength, low strain-to-failure and low plasticity. However, the ductility and formability of the material represent a limitation for the clinching process. The present study explored some concepts of clinching, such as hole, friction-assisted, laser-assisted, electro-hydraulic, electromagnetically assisted and hot assisted clinching, for the difficult-to-form sheets. The paper includes the description of the deformation mechanism of clinched joints and the analysis of clinched joint performance and applicability.

“…The failure modes and damage process of CFRP under bending load are studied to improve the anti-damage performance and guide the design of clinching tools. Dean et al [69] developed and built a 3D FEM-based virtual test-rig tool for the hybrid metal-composites clinching technology. Experimental results concerning the hybrid metal composites clinching were presented for the hybrid pairing of aluminum EN AW-5754 and short fiber-reinforced plastic composite PA6GF30.…”

Clinching technology is a mechanical connection technology that is applied to connect metal or non-metal sheet materials. It is widely used in different applications, such as automobile, aircraft, household appliances and other industries. In order to reduce weight, save energy, reduce fuel consumption, reduce pollution and curb global warming, lightweight structures with clinched joint are increasingly used in transportation. The finite element technology is popularized in engineering, so that it can get similar results with the test after investing less time, manpower, energy and material resources, which is conducive to the prediction and smooth progress of the test. A review of the finite element analysis of clinching technology is provided in the present paper. The article's work also discusses the strength of the clinched joint, the factors influencing the clinched joint's strength, the failure mechanism of the clinched joint, etc. Furthermore, the novel technologies of clinching as well as the finite element models and methods used in clinching, are introduced. The present paper's main objective was to review the recent developments in the finite element analysis of clinching and provide a basis for further investigation in this area of research.

“…As illustrated in Figure 1, this system comprises three key elements: the bumper beam, the absorber, and the fascia [17][18][19]. Lightweight materials have garnered significant attention in automotive applications, primarily due to the trend of replacing heavy parts to conserve fuel and reduce carbon footprint [20][21][22][23][24][25][26][27][28][29][30][31][32][33]. However, it is worth noting that the energy required to propel a vehicle is more than ten times the energy used in the manufacturing process [34].…”

The bumper beam is a crucial component of the automobile bumper system, responsible for absorbing impact energy and enhancing the safety of passengers during collisions. This paper presents the design and experimental analysis of a 3D-printed composite–plastic hybrid light structure, designed as a collapsible energy absorber. Exploratory testing was conducted using low-impact tests to investigate the failure mechanism and energy absorption capacity of a spiral structure. The design process involved optimizing the spiral diameter by testing specimens with varying diameters between 0.5 cm and 2.5 cm, while keeping other geometric parameters constant. The study employed three types of 3D composite structures, including printed thermoplastic, printed thermoplastic reinforced with Kevlar fiber composite, and printed thermoplastic filled with foam. The thermoplastic–foam composite with nine spirals (diameter = 0.97 cm) yielded the best results. The new design demonstrated high energy absorption capacity and a controlled and progressive failure mechanism, making it a suitable candidate for energy absorption applications.
