SUMMARY
In this paper, a modeling and numerical simulation for the double cormgated cardboard plates is
presented. The proposed modeling allows us to predict the mechanical behavior of the corrugated
cardboard plates without carrying out the experiments. This model was validated by comparing the
experimental results with the simulation results using Abaqus software for the single and double
corrugated cardboard plates in bending. The model can be used not only for bending simulation,
but also for traction, shearing, and torsion simulation.
Keywords: modeling, corrugated cardboard, orthotropic plates.
INTRODUCTION
Nowadays, the corrugated cardboard is
widely used in the packaging industry. It is
essential to predict the mechanical behavior
of such materials. For this reason, it is
necessary to carry out a lot of test with many
types of corrugated cardboard, this is too
tedious and costly. Thus, it is necessary to
execute the modeling and numerical
simulation of such 3D composites. By using
some FE models and commercial FE
software, some authors studied the
mechanical behaviors of corrugated cardboard
[1-5], but it just limited with the single
corrugated cardboard.
The corrugated cardboard is produced by a
converting process in which three or more
layers are laminated together. The flat layers
are called liners and the corrugated cores are
referred to as flutes (Fig. 1). Corrugated
cardboard is one of the most used packaging
materials to make boxes or interlayers for
goods transport. The manufacturing process
gives three characteristic directions: the
machine direction {MD), the cross direction
{CD), and the thickness direction {ZD).

This paper presents a shell 3D model for the
mechanical behavior of a corrugated
cardboard composed of three or five layers
(single or double flutes). The simulations in
bending using Abaqus software for single and
double corrugated cardboard plates will be
studied in this paper. This 3D model has
very close results comparing to* the
experimental results.
MODELING FOR THE CORRUGATED
CARDBOARD
To model the corrugated cardboard panel, we
use a commercial finite element software
named Abaqus which has very strong
capacity in the modeling and numerical
simulation. We first create a panel of
corrugated cardboard as shown in the Fig 2
by using the drawing tools in the Part
Module.
