Abstract (EN): The use of bonded joints in industrial applications has been increasing in recent years, to the detriment of traditional bonding methods such as welding, brazing, and bolted and riveted joints. In many practical situations, such as vehicle crashes, adhesive joints are subjected to impact loads. However, the knowledge on the joint behaviour for this loading is much less addressed in the literature that the typically studied static case. This work focuses on a numerical study, through cohesive zone modelling (CZM), of tensile loaded joints in impact scenarios with three adhesives with distinct properties. Initial comparison with experimental data was undertaken. The single-lap joint (SLJ) geometry was chosen as it is the most used bonded joint. Three-dimensional (3D) modelling and different adherend materials, including carbon-fibre reinforced plastic (CFRP), were evaluated as well. The numerical technique showed a good correspondence to the test results. The CZM analysis enabled finding the best set of material/adhesive conditions to provide the best results under impact loadings.
