Abstract

The aim of this work a three dimensional stress analysis of hybrid joints using different materials. Hybrid joint
was designed both adhesively bonded and pinned single lap joints. Aluminum, copper, steel and titanium were
selected as adherent materials, whereas the epoxy resin was preferred for adhesive. Three dimensional finite
element models have been created to obtain stress distributions using ANSYS software. After the modeling and
meshing process, both pinned boundary condition with tensile loading and uniform temperature were performed
for double loading conditions on the model. It is understand that the positions of stresses were considerably
affected from existence of pin hole, so stresses were concentrated around it. Additionally, steel adherents cause
higher stresses than other used materials. The titanium adherents provided lower stresses.
