Dataset assigned to paper 'Experiments and Numerical Modeling of Dynamic Compressive Response in Auxetic Lattices 3D Printed from 316L Stainless Steel'

This dataset accompanies the manuscript 'Experiments and Numerical Modeling of Dynamic Compressive Response in Auxetic Lattices 3D Printed from 316L Stainless Steel'. It contains the data used for the presenation of experimental and numerical results generated in the investigation of the mechanical and microstructural response of three types of auxetic lattices subjected to uni-axial compressive loading. The investigated lattices (2D missing-rib, 2D re-entrant honeycomb, 3D re-entrant honeycomb) were LPBF printed from 316L steel and subjected to loading at different strain rates ranging from quasi-static regime to loading in SHPB apparatus. The dataset includes experimental and numerical stress-strain diagrams, functions of Poisson's ratio, SHPB force-equilibrium records, design geometry of the lattice scalable and editable to final desired dimensions in STL format, reconstructed 3D images from XCT scanning in RAW format, and data derived from pore space analysis in the reconstructed 3D images. The data support the experimental characterization and numerical analysis presented in the publication. The dataset consists of data files together with a README.pdf file describing the dataset structure, file contents, and the relevant data channels used for the analysis.
