Abstract
Dissimilar connections with aluminum EN AW-6016 and high strength steel CR330Y590T-DP are affordable and promising regarding lightweight potential. Self-piercing riveting (SPR) and structural adhesive enable an assembly of such dissimilar combinations. This study provides an approach to assess hybrid joints by superposing the contributions of each joining technique on the resulting fatigue life. The fatigue life estimation of SPR is based on a structural stress approach and material SN curves. For the adhesively bonded connections, a stress-based approach and a master SN curve are used. Both of the approaches for fatigue life estimation show a reasonable agreement with test data.
