Effective compressive elastic behavior of rhombic dodecahedron structure with and without border constraints

The effective compressive elastic modulus of the cellular rhombic dodecahedron structure, with m × n cells in the X- and Y- directions in matrix, has been studied. The effective compressive elastic modulus of the structure without border constraint is a function of m and n; while for the structure with border constraints in the X- and Y- directions it is found unique that is independent of m and n, and is a function of the porosity of the...
