This paper assessed a shear behaviors of a single lap adhesive joint experimental and
numerically under room, high and low temperatures by using aluminum as adherent and
epoxy (G-flex) as adhesive.
Before performing the single lap shear tests, a Finite Element Analysis (FEA) model with
ABAQUS software program was created simulating the shear strain occurring during the test.
In the FEM analysis a Cohesive Zone Model (CZM) was adopted. The adhesive joint
thickness was supposed to be zero. The cohesive parameters of elastic linear stiffnesses
and damage initiation stresses and then damage evolution fracture energies in mode 1,
mode 2 was entered with accepting that parameters in mode 3 to be equal to those of mode2
in order to simplify the model as possible.
Two different tests Double Cantilever Beam (DCB) and End Notch Flexure (ENF) were
fulfilled according to ASTM standards to find the mode 1 and the mode 2 fracture energy
parameters. The rest of parameters were estimated numerically by fitting the experimental
Load-displacement curve to the numerical one.
