Abstract

Gyroid is a member of the triply periodic minimal surfaces (TPMS) family. In this paper, the mechanical properties of Gyroid-structures are investigated both experimentally and computationally. 3D printing is used to fabricate polymeric Gyroid-structure specimens made of PA 2200 at different relative densities. In the finite element analysis, the Arruda-Boyce finite-deformation elasto-viscoplastic model is employed. To perform the finite element analysis, the properties of the 3D printed material are determined by a series of tension and compression tests. The finite element results of the Gyroid-structure agree very well with the experimental data. Also, the uniaxial modulus, compressive strength, and energy…
