DOI: 10.1016/j.ijfatigue.2020.105946
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… read more here.

DOI: 10.1080/15376494.2019.1629048
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,… read more here.

DOI: 10.1103/physreve.106.015004
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… read more here.
