Dataset accompanying the manuscript "Finite element modeling of a nominal tetrachiral lattice under quasi-static compression with preliminary insights into manufacturing-induced geometric deviations"

This dataset accompanies the manuscript "Finite element modeling of a nominal tetrachiral lattice under quasi-static compression with preliminary insights into manufacturing-induced geometric deviations". It contains the experimental and numerical data used in the investigation of the mechanical response of a chiral structure under compressive loading. The dataset includes raw experimental force–displacement records from three independent tests, the three-dimensional CAD geometry of the investigated structure in STEP format, and the Abaqus finite element model used for the explicit numerical simulations reported in the accompanying manuscript. The data support the experimental characterization and numerical analysis presented in the publication. The dataset consists of five data files (Experimental_ForceDisplacement_S1.txt, Experimental_ForceDisplacement_S2.txt, Experimental_ForceDisplacement_S3.txt, CAD_Model_Chiral.stp, and Abaqus_Model_Chiral.cae) together with a README.md file describing the dataset structure, file contents, and the relevant data channels used for the analysis.
