Abstract

This paper investigated the shear behavior of a single lap adhesive joint of two aluminum parts bonded with

epoxy G/flex 655 adhesive.

A finite element analysis model with the ABAQUS software program was created to simulate the shear strain

occurring during the test. A Cohesive Zone Model (CZM) model was adopted and replaced by a mathematical

model of the adhesive‟s mechanical and damage parameters

The realization of two tests have required to get fracture energies GI, GII of mode1and mode 2 respectively

before entering the necessary of data.

Double cantilever beam (DCB), and the End Notched Flexure (ENF) tests were performed according to ASTM

standards to find the GI, GII values as mentioned above.

The parameters of elastic linear stiffnesses and damage initiation stresses in mode one and two were entered by

fitting numerically with the experimental curve, and then mode 3 parameters were accepted to be equal to those

of mode 3 since in both of them occur shear even in different ways, in order to simplify the task as possible.
