2D Mathematical Model of Damping in Cellular Materials

Many biological materials may be considered as cellular materials, for example, soft tissues, but also bones, wood, or foam-like medulla in a bird feather. The cells filled with fluid just air, have different size, shape, and wall thickness. Less is known about how the mechanical morphological parameters of influence their biologically relevant functions. A simple descriptive 2D numerical model material based on Voronoi diagrams presented here which aims prompt investigation structural its physical properties. preliminary simulations demonstrate that an increasing thickness energy dissipation increases cell density average stress increases. Other interesting results are increased constant reduces stress, hierarchical foams takes place mostly thick walls. approach allows screening further features parameters, such kinds gradients properties inspired at loading conditions. Direct comparison real structures could performed, especially when experimental measurements impossible.
