Triply Periodic Minimal Surface (TPMS) are porous structures that have attracted the attention of a large number of researchers due to the exceptional properties they offer. In this study, we focus solely on one TPMS structure, which is the IWP structure (« I-graph Wrapped Package»). This structure exhibits cubic symmetry and is interconnected and intertwined in three-dimensional (3D) space. In this paper, we studied the deformation energy absorbed by the IWP structure by increasing the relative density and the number of cells, in order to determine the influence of these parameters on the energy absorption rate. To determine this rate, we conducted elastoplastic simulations using ABAQUS software for a uniaxial tension case. We found that the energy absorption rate of the IWP structure is influenced by and proportional to both the relative density and the number of cells. This rate increases with the increase of either of these parameters, or both simultaneously.

摘要

Triply Periodic Minimal Surface (TPMS) are porous structures that have attracted the attention of a large number of researchers due to the exceptional properties they offer. In this study, we focus solely on one TPMS structure, which is the IWP structure (« I-graph Wrapped Package»). This structure exhibits cubic symmetry and is interconnected and intertwined in three-dimensional (3D) space. In this paper, we studied the deformation energy absorbed by the IWP structure by increasing the relative density and the number of cells, in order to determine the influence of these parameters on the energy absorption rate. To determine this rate, we conducted elastoplastic simulations using ABAQUS software for a uniaxial tension case. We found that the energy absorption rate of the IWP structure is influenced by and proportional to both the relative density and the number of cells. This rate increases with the increase of either of these parameters, or both simultaneously.
