000014936 520__ $$2eng$$aWe use a non-destructive imaging technique to examine the mechanisms of damage initiation and failure evolution of aluminium alloy lattices with either rhombicuboctahedron or regular octet topology under quasi static compression. Results show that each lattice exhibits its own failure mechanism. For the rhombicuboctahedron topology, failure initiates on the top layer of the lattice sample before propagating into the neighbouring layers, thereby resulting in a layer-by-layer crushing mechanism. For the regular octet lattice, damage initiates at the interior surfaces , thus generating an apparent dislocation plane that splits the sample into two portions along a 45 degree plane. From tomography image reconstruction, geometrical imperfections, originated during the manufacturing process, were extracted, morphologically identified and statistically quantified. The probability values of each set of deviations were subsequently used to build realistic full-size finite element models that help elucidate the failure mechanisms and damage evolution observed during the experiments.
