| Abstract Scope |
Beam lattices are a subset of architected materials comprising a network of beam-like struts or rods arranged in a specific geometry or pattern. This work presents the experiment and simulation study of new body-centered cubic (BCC) beam lattices made of reinforced I-beams. The lattices will be fabricated using a J35 Pro 3D printer. To demonstrate the improved mechanical properties, conventional BCC lattices with circular beam cross-sections are also fabricated. We will perform quasi-static compression tests to study the crushing behaviors of the lattices. The stiffness, strength, and energy absorption will be extracted from the measured stress-strain curves. Additionally, we will perform finite element (FE) analysis using Abaqus to simulate the compression tests. The FE model will be created using shell elements to reduce the computational costs. The elastoplastic material model calibrated from experiments will be employed in the FE model. The general contact will also be considered to account for the effects of beam contact during the compression tests. Based on the previous study, we expect that the proposed new lattices will enhance by at least 100% in stiffness, 50% in yield strength, and 200% in energy absorption compared to conventional BCC beam lattices. |
