3D-auxetic-truss-lattice-materials

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

Architectures shown in the publication "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"

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.
• 2. AUTOLisp Files - Used for the parametric generation of unit cells with periodic boundary conditions.
