摘要
In this paper, the physical and mechanical properties of products with the geometry of a triply periodic minimal energy surfaces (TPMES) are studied by computer simulation. The calculations are performed by the FEN method (hyperelastic viscoplastic fracture with a finite deformation) for typical samples of polyamide-12 material obtained by selective laser sintering (SLS). As a result of the study using the Comsol Multiphysics program, the distribution of mechanical stresses and the appearance of deformed products at various values of the applied mechanical stress, as well as the deformation curves, were obtained. The convergence of the calculations on the mesh size of the model under study is shown. The simulation results are in close agreement with the experimental data. As a result of the study, excellent physical and mechanical characteristics of the samples with the proposed geometry are found.
