Elastic Modulus of Rhombus Dodecahedron Closed-Cell Cellular Materials

Abstract:

Based on the pore formation principle, geometrical model to describe cellular materials was constructed. The model is closed-cell rhombus dodecahedron with thick edges. The dependence of relative density on microstructure parameters and the unitary relation have been obtained. By finite elements method, the relative elastic modulus was simulated, the influence of microstructure and relative density on elastic modulus was analyzed. The results show that the wall-face connective curvature radius is the primary affecting factor of relative density increment and the wall-thickness is less significant; the solid materials added at the intersecting part of the wall-faces produce same effect on elastic modulus. The conclusion can be applied in optimization design of cellular materials.
