3D-auxetic-truss-lattice-materials

Repository of scripts for the parametric generation of auxetic truss lattice materials

Architectures shown in the publications:

  1. "Vitalis, T., Gross, A. J., and Gerasimidis, S. (June 4, 2024). "Mechanical response and failure modes of three-dimensional auxetic re-entrant LPBF-manufactured steel truss lattice materials." ASME. J. Appl. Mech. doi: https://doi.org/10.1115/1.4065669"

  2. "Vitalis, Thomas, Andrew J. Gross, Georgios Tzortzinis, Brian Schagen, and Simos Gerasimidis. (December 3, 2024) “Enhancing Mortar Composite Matrices with Three-Dimensional Auxetic Truss Lattice Materials for Reinforced Concrete Structures,” Construction and Building Materials. doi: https://doi.org/10.1016/j.conbuildmat.2024.139165"

Figure Experiment videos available online

All unit cells are tetragonal.

Filetypes Included:

    1. Rhinopy Files - Used for the parametric generation of finite-sized auxetic truss lattices along with the Rhino/Python API.
    1. AUTOLisp Files - Used for the parametric generation of unit cells with periodic boundary conditions.
