Abstract:	The main objective of this research is to investigate the influence of structural parameters and relative density on the geometric characteristics and equivalent elastic modulus of TPMS structural materials in a wide range of relative densities. The three dimensional numerical models for four typical TPMS structural materials are established, and the corresponding finite element simulations are performed for uniaxial compression tests. The results show that the structural parameters can directly control the geometric characteristics of the cellular structure, and also the equivalent elastic modulus of the structural material through the relative density as an intermediate variable. The equivalent elastic modulus and relative density increase with the increase of structural parameters, and change to a certain extent near the open closed pore transition. This study can provide some understanding for the design and application of TPMS structural materials.
