| This paper concerns the numerical modelling of the mechanical properties of metamaterials with a gyroid mesostructure and various relative densities, obtained using the additive laser powder bed fusion (LPBF) method from CoCrWMo alloy. The paper presents and compares two approaches to modelling the deformation process of the investigated metamaterials. The first was based on nominal geometric models of gyroid mesostructures, while the second involved mapping realistic mesostructure shapes using X-ray micro-computed tomography (micro-CT). The use of tomographic measurements made it possible to take into account the imperfections and defects of the studied gyroid structures resulting from the characteristics of the production process and its parameters. Using both approaches, numerical modelling of the deformation process of the investigated metamaterials was carried out using the finite element method (FEM). Based on the numerical calculations, stress and strain distributions in the studied metamaterials were obtained, and after their analysis, the influence of the shape of the tested mesostructures and their imperfections on their mechanical properties was determined. It was also indicated how external and internal technological defects can affect the mechanism of material fracture. A verification of the developed computational models was also performed using the results of experimental studies. |
