Stiffness of Case Furniture Made of Layered Cellular Boards with an Auxetic Core - Numerical Approach

Auxetics are materials and structures characterized by anomalous shrinkage properties during compression and swelling during stretching. They are called negative materials due to their negative Poisson's ratio. Such materials have not yet found applications in industrial practice. Therefore, in this study it was decided to demonstrate the influence of sandwich honeycomb panels with the auxetic core on stiffness and strength of cabinet furniture. The research was carried out using the finite element method in the Abaqus program. The calculation results were compared with the data obtained for furniture made of conventional particle boards. It has been shown that auxetic cellular panels have a positive effect on mechanical properties of furniture subjected to torsion and bending.
