“…Although the relationship between different strengths of an SPR joint varies with different joint stacks, the values stated by these authors are reasonable. Recently, Haque and Durandet [141] also carried out a similar study and their predicted cross-tension and lap shear strength of SPR joints could match the tested strength reasonably.…”

Self-piercing riveting (SPR) is a cold mechanical joining process used to join two or more sheets of materials by driving a rivet piercing through the top sheet or the top and middle sheets and subsequently lock into the bottom sheet under the guidance of a suitable die. SPR is currently the main joining method for aluminium and mixed-material lightweight automotive structures. SPR was originated half century ago, but it only had significant progress in the last 25 years due to the requirement of joining lightweight materials, such as aluminium alloy structures, aluminium-steel structures and other mixed-material structures, from the automotive industry. Compared with other conventional joining methods, SPR has many advantages including no pre-drilled holes required, no fume, no spark and low noise, no surface treatment required, ability to join multi-layer materials and mixed materials and ability to produce joints with high static and fatigue strengths. In this paper, research investigations that have been conducted on self-piercing riveting will be extensively reviewed. The current state and development of SPR process is reviewed and the influence of the key process parameters on joint quality is discussed. The mechanical properties of SPR joints, the corrosion behaviour of SPR joints, the distortion of SPR joints and the simulation of SPR process and joint performance are reviewed. Developing reliable simulation methods for SPR process and joint performance to reduce the need of physical testing has been identified as one of the main challenges.

“…12, the averaged cross-tension strength of three joints was measured as 2.52 kN, and the cross-tension strength obtained from FE model simulation is 2.69 kN, while the predicted strength value of SPR-C joint obtained from the XGBoost regression model is 2.71 kN, and a prediction error of 7.6% is observed between experimental and predicted strengths, which indicates that the established XGBoost regression model can effectively predict the cross-tension strength of SPR joints. Haque et.al [9] proposed an empirical model on the basis of characteristic force-displacement curves during SPR process, in which two critical empirical parameters depending on hardness and length of rivet were involved. Although a prediction error smaller than 8% was achieved for the cross-tension strength of SPR joint, the empirical model by Haque et.al [9] relied heavily on the selection of empirical parameters and a considerable number of experimental data.…”

“…Nine different cases consisting of aluminium and steel materials with various thicknesses and strength grades were examined to validate the model. Later, an empirical equation without using cross-sectional dimensions of SPR joints was established by Haque et al [9]. The empirical equation can achieve the prediction of cross-sectional dimensions and lap-shear strengths directly based on the force-displacement curve of SPR process, and the predicted strengths of SPR joints matched the experimental strengths reasonably.…”

Self-piercing riveting (SPR) has been widely used in automobile industry, and the strength prediction of SPR joints always attracts the attention of researchers. In this work, a prediction method of the cross-tension strength of SPR joints was proposed on the basis of finite element (FE) simulation and extreme gradient boosting decision tree (XGBoost) algorithm. An FE model of SPR process was established to simulate the plastic deformations of rivet and substrate materials and verified in terms of cross-sectional dimensions of SPR joints. The residual mechanical field from SPR process simulation was imported into a 2D FE model for the cross-tension testing simulation of SPR joints, and cross-tension strengths from FE simulation show a good consistence with the experiment result. Based on the verified FE model, the mechanical properties and thickness of substrate materials were varied and then used for FE simulation to obtain cross-tension strengths of a number of SPR joints, which were used to train the regression model based on the XGBoost algorithm in order to achieve prediction for cross-tension strength of SPR joints. Results show that the cross-tension strengths of SPR steel/aluminum joints could be successfully predicted by the XGBoost regression model with a respective error less than 7.6% compared to experimental values.

“…SPR joints have superior static and fatigue properties, while clinched joints also present favorable fatigue performance [12]. Higher strength is always observed in lap-shear testing compared with crosstension testing [13]. As part of structural crashworthiness, dynamic tests are needed to study the dynamic behaviors of joints.…”

e present work compares the dynamic effect of a self-piercing riveted (SPR) joint with that of a mechanical clinched joint having the dissimilar materials combination. e substrates used in this investigation are aluminum alloy AA5182-O and deep drawing steel DX51D+Z. e static and dynamic behaviors and the failure modes of the SPR and clinching joints are characterized by lapshear, cross-tension, and coach-peel tests. e influence of the strain-rate-dependent mechanical behavior of the substrates on the joints is examined; this can help improve prediction of the energy absorption of the joints under impact loading. Considering the realistic baking process in a painting shop, the deforming and hardening effects on the SPR and the clinched joints induced by baking are also studied. e specimens are heated to 180°C for 30 min in an oven and then cooled down in air. e SPR and the clinched joints before and after the baking process are compared in terms of the mechanical behavior.
