Exploring the Dependencies of Poisson’s Ratio in Auxetic Structures
May 11, 2026
Grünfelder, Nicolas; Pi Savall, Berta; Seyedpour, Seyed Morteza; Waschinsky, Navina; Ricken, Tim, 2026, "Exploring the Dependencies of Poisson’s Ratio in Auxetic Structures", https://doi.org/10.18419/DARUS-4322, DaRUS, V1
In this repository, an Abaqus Python scripting approach for a natural frequency analysis of an auxetic lattice structure is presented. The script "Modal_4x4x4_Lattice.py" produces an input file for Abaqus that controls all necessary preprocessing and simulation steps. Additionally, for the first step of postprocessing, all needed results are extrac...
Replication Data for: Shape Optimization of auxetic unit cells under dynamic loading in macroscopic components
May 11, 2026
Grünfelder, Nicolas; Kälber, Lars; Waschinsky, Navina; Ricken, Tim, 2026, "Replication Data for: Shape Optimization of auxetic unit cells under dynamic loading in macroscopic components", https://doi.org/10.18419/DARUS-4777, DaRUS, V1
In this repository, an Python scripting approach for a Bayesian shape optimization, with an Abaqus implimentation for solving for natural frequencies and harmonic response simulation, is presented. The script "Shape_Opt_Master.py" controls all the necessary functions and contains the optimization as a wrapping function around the Abaqus simulations...
