An efficient homogenization model for the corrugated cardboard has been developed. In our H-model, the corrugated cardboard is represented by a 2D plate. Instead of using a local constitutive law (relating the strains to the stresses) at each material point, the homogenization process leads to a generalized constitutive law (relating the generalized strains to the resultant forces) for the equivalent homogeneous plate. Our H-model was implemented into the finite element software ABAQUS. The foam behaviour was experimentally determined and modeled with a crushable foam model of ABAQUS. The drop tests were performed as a free fall from a given height onto a rigid floor. The acceleration of the packed product was recorded using a triaxial accelerometer. The numerical results obtained using the FE simulation with our H-model agree very well with the experimental results. We have also shown that the contribution of the corrugated cardboard box to the shock response is very important.
