Abstract

The aim of this study is to investigate effects on stresses of using different
adherent material in metal-composite hybrid joints. It was assumed that a composite
plate was adhesively bonded and pinned to different metal plates. The metal plates were
aluminum, steel, copper and titanium. For providing a real problem, three-dimensional
finite element models were created. Tensile loads at uniform temperature were tested on
the modeled hybrid joints. In order to analyze the stresses of the problem, the finite
element method (FEM) was chosen, since this method has proved suitable for solving
many engineering problems recently. According to the results, high stresses occurred
because of the different material properties of the composite adherent, metal adherent
and epoxy adhesive. Stresses were concentrated around the pin hole zone especially. The
higher stresses were observed for the steel-composite joint, whereas the lower stresses were
obtained in the titanium-composite joint.
