Abstract: Abstract Laser Powder Bed Fusion (L-PBF) provides ample freedom to fabricate lattice materials with tailored micro-architecture. Nevertheless, small-scale structures often suffer from a wide range of morphological defects, which impact the macro-scale mechanical properties. In…

Abstract: Abstract Natural materials often feature hierarchical architectures which result in remarkable mechanical properties. Bio-inspired hierarchical architected materials can be designed and fabricated using 3D printing technology, but the underlying mechanisms on how to manipulate mechanical…

Abstract: Abstract This paper presents a systematic approach for designing 3D auxetic lattice materials, which exhibit constant negative Poisson’s ratios over large strain intervals. A unit cell model mimicking tensile tests is established and based on…

Abstract: Abstract We propose a methodology to parameterize lattice materials with octahedron-based structures. Transverse-isotropic octahedral repeatable-volume-elements (RVEs) with three mutually perpendicular planes are used to produce periodically arranged structures in 3D-space by translation. In this way,…

Abstract: We examine how disordering joint position influences the linear elastic behavior of lattice materials via numerical simulations in two-dimensional beam networks. Three distinct initial crystalline geometries are selected as representative of mechanically isotropic materials with…

Abstract: Lattice materials can be designed through their microstructure while concurrently considering fabrication feasibility. Here, we propose two types of composite lattice materials with enhanced resistance to buckling: (a) hollow lattice materials fabricated by a newly…
