A novel lattice structure with Y-shaped cores was designed and fabricated using 3D printing technology for quasi-static compression tests. Numerical simulations were conducted to investigate the mechanical properties and failure behavior of the lattice structure. The results of the simulations agreed well with the experimental results, revealing the failure processes and mechanisms of structures with different relative densities.
In this study, a novel lattice structure with Y-shaped cores was designed. Specimens of the structure were fabricated using 3D printing technology for quasi-static compression tests. Numerical simulations were also performed to investigate the mechanical properties and failure behavior of the lattice structure. The numerical results are in good agreement with the experimental results. The numerical simulations are used to reveal the failure processes and failure mechanisms of structures with different relative densities. The results show that the relative density has significant effects on the mechanical properties of the lattice structure, and that different methods of changing the relative density lead to different results.
