Numerical simulations of gyroid structures under compressive loads

Abstract

Numerical simulations of gyroid structures under compressive loadsNumerical simulations are essential for predicting the mechanical properties of new materials, structures, and final products. In the case of triple periodic minimal surface structures, particularly gyroids, predicting the mechanical behaviors beyond the elastic region is difficult, especially under high strains. This work addresses this issue and introduces a method to predict the mechanical behaviors of gyroid structures using the finite element method. In addition, the mechanical properties of the constitutive material are determined experimentally.Furthermore, different methods are explored, including the use of shell elements, solid elements, and homogenization. Results reveal that homogenization is more suitable for obtaining the properties in the elastic zone, whereas solid models are better for determining the behaviors in the plateau zone and the densification point.
