Abstract: By taking advantage of the characteristics of the cube's diverse changing modes and ignoring the influence of the spherical volume of the Rubik's slide rail, the subblocks of the cube are replaced with porous units. Through modeling, simulation and calculation, the elastic modulus of the Rubik's Cube-like composite structure under different programming modes is studied. Finally, it is verified that under the same forming material, the Rubik's Cube-like composite structure can effectively regulate its overall elastic modulus by changing its combination mode. The larger the difference in the volume fraction of the subunits, the larger the elastic modulus span of the whole structure, and the elastic modulus of the face-centered cubic lattice is larger than that of the cubic lattice span. When the ratio of upper and lower volume fraction of the face-centered cubic lattice substructure is 1∶9, the elastic modulus of the whole composite structure is minimum 2.2 MPa and maximum 54.29 MPa. The porous Rubik's Cube structure proposed in this work is expected to realize multiple programmable elastic moduli of the same substructure, and can be used as a multi-functional material in medical, aerospace, mechanical manufacturing and other fields.
