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: 10.1126/sciadv.adv2023
Abstract: Schemes for exploring light-induced phenomena rely on uniform and diffraction-limited free-space optics, which limits spatial resolution and efficiency of light-matter interaction. We overcome these challenges using metasurface plasmon polaritons to form a sub-wavelength optical lattice. read more here.
