Effects of Using Different Metal Materials on Stresses in Metal-Composite Hybrid Joints

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.
