Numerical Simulation for the Folded Core Sandwich Plates under Torsion by Homogenization Method
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 10
Abstract
In this paper, an analytic homogenization model for the torsion problem of folded core sandwich plates is presented. It is very difficult to determine the torsion rigidity of these kinds of 3D structures even numerically because of the boundary condition effects. Based on the gridwork homogenization model of Timoshenko, plate torsion is divided into two beam torsions. The plate torsion curvature is separated into two beam torsion rates and the beam torsion rigidities in these two directions are introduced to describe the torsion behavior of the orthotropic plates. The proposed analytical homogenization model allows replacing the 3D folded core sandwich by a 2D homogenized plate. This model is validated by comparing the results of Abaqus3D and H-2D homogenization model, confirming the accuracy and effectiveness of the proposed model. This torsion homogenization model can be used not only for corrugated cardboard packaging structures, but also for naval and aeronautic composite structures.
