Mechanical performance of pinned composite/metal joints under tension

This dissertation analyzes a novel composite to metal joining technology called pinning, by utilizing mechanical testing and numerical simulation on coupon level. Special focus is given to the investigation of fiber undulations and their impact on the mechanical performance of the pinned composite/metal joint. Fiber undulations around the pins lead to a more homogeneous strain and stress distribution within the composite when compared to conventional mechanically fastened joints with drilled holes.
