U.S. interstate and air traffic maps: creating a multilayered lattice material as a component within nonlinear structures

Architected materials have a wide scope of applications in material science but have a strong potential as a part of the system in structural engineering. They also provide an opportunity to investigate behavior of microscale structures at a macro-scale, a system within systems. The geometrical design of multi-layered randomized architected material (MLRAM) is harnessed through Latin Hypercube Sampling. The material specimens are 3D printed using Stratasys Objet500 Connex3 printer with Vero Cyan as the printing material. Experiments are conducted to obtain the tensile properties of this newly developed material. This paper presents a computational model that captures the tensile behavior of the proposed material using a non-linear finite element method. A framework is created which captures the progressive failure of the links of the MLRAM.
