Abstract

Bonded assembly is a widely used technique especially in the aerospace industry. This work aims to study the behavior of a bonded assembly-type metal/metal under tensile loading. A numerical investigation with the code (FEM Abaqus) was carried out to evaluate the resistance of a single-lap adhesive-bonded joint, highlighting several parameters namely: loading, thickness of adhesive, and overlap length. The geometric model for the single-lap adhesive-bonded joint used is made of two thin steel plates, with different adhesive types. The results obtained by the finite element method show that the optimum overlap length (O-L = 10 mm) is the length of the adhesive that allows it withstand a maximum force for a minimum adhesive surface.

Key Words
