The file contains images and Ncorr files for the image analysis of the physical tests and Ansys and data files to run the FEA models for as tested cells, isotropy analysis and the optimisation and setup of the individual cells. The four parts of the data set are: 1) the images and n_corr session data used to assess the Poisson's ratio of the samples with image analysis; 2) the Finite Element models used during the optimisation of the base cells in various stages, with infinite simulation boundary conditions and the output values; 3) the flat angle form of the Finite Element models to allow re-creation of the isotropy tests for each lattice; 4) the as-tested FEA models to allow re-creation of the validation simulations for the physical testing process. 2023-04-12 University of Bath public This data is the finite element files, image files and ncorr settings used in the development and analysis of a set of experimental auxetic lattice structure unit cells. RightsHolder University of Bath University of Bath https://doi.org/10.13039/501100000835 Studentship artai The four sections of the data have separate methodology: - The as-tested FEA are 3D models close to the physical test samples loaded with fixed boundary conditions to emulate the way the cells were loaded during testing and allow direct comparison. - The isotropy study is a global level cell model for each type of lattice, with a variable loading and boundary vector. - The optimisation study has the infinite grid simulation boundary conditions and includes the optimisation methods. Also included are the cell models based on literature which were not optimised in this study but were studied in comparison. The numerical methods and data that it produced are also included. - The images and Ncorr files used to assess them are also included to replicate physical testing. More details can be found in the paper itself. The files require Matlab R2020b with Ncorr (https://ncorr.com/) and Ansys Workbench 2021R2. https://doi.org/10.1016/j.matdes.2023.111844 2021-02-01 2021-12-17 en 1 10.15125/BATH-01164 https://doi.org/10.1016/j.matdes.2023.111844 pub open Dataset
