Kurzfassung
Because of a planar load introduction, a high strength over weight ratio, avoidance of holes, corrosion resistance and component reduction, adhesively bonded joints attract increasing attention in lightweight construction. Nonetheless, a reliable prediction of the joints’ behaviour in terms of stress and strength is still a tremendous challenge.In this study the eXtended Finite Element Method (XFEM) in combination with cohesive behaviour is used to model crack growth under quasi-static loading. The objective of this work is to study the influence of different continuum mechanical material models for the adhesive on XFEM strength predictions. It will be evaluated whether the strength prediction of joints mainly loaded in shear is more accurate with a high sophisticated material model. Therefore, strength predictions of Single Lap Joints (SLJ) with thick aluminium adherends are performed. Herein, digital image correlation (DIC) data recorded during experimental tests are used to assess the material models in combination with the derived material parameters. Furthermore, with the experimental results the performed strength predictions are evaluated. It could be revealed that XFEM in combination with a suitable yield criterion and appropriate material parameters is a valid technique for the strength prediction of lap shear joints since the variance to the experiments is less than 1 %.
