This paper presents an investigation on the modelling of flow-drill screw connections in thin-walled aluminium plates in large-scale finite element analyses using different macroscopic modelling techniques. Five models that were originally developed for adhesive bonds, spot welds and self-piercing rivet connections were examined. Two sets of experimental data were used, each with a different screw and material combination. Different trends were observed for the two sets, which challenged the flexibility of the models. The results indicated that a constraint-based model originally developed for self-piercing rivet connections was the best suited model. A two-step validation strategy was proposed and used for the present models.
