Abstract Scope |
Additively manufactured latticed structures have been widely employed in light-weighting structures as they exhibit outstanding potential for manufacturing tunable characteristics. One of the key tools for studying these lattices' deformation and failure behaviors is finite element modeling. However, due to the stochastic nature of the defects generated during manufacture, today’s finite element modeling cannot perfectly predict the lattices’ mechanical performance. In the present work, a methodology is developed for more precise performance prediction. X-ray micro-computed tomography was used to visualize the internal defects in the printed samples. The reconstructed structures were then used to assess the printing fidelity and study their impact on the mechanical properties. To further quantify the mechanical response, FE analysis was conducted based on data extracted experimentally from standard quasistatic tensile tests and 3D reconstructions. The experimental results were then compared to the results from the FEA for validation. |
