Description
The dataset contains structure-property data for strut-based lattices. The lattices are based on structures from RCSR and EPINET databases, as presented in paper doi.org/10.1073/pnas.2003504118.
The original family of lattices was filtered and expanded using our python code. Structural properties (compliance tensor) were calculated at various relative densities using ABAQUS simulations.
The scripts that can be used to reproduce the data are included in the repository. Please see README.html or README.md for detailed instructions.
Version
Software / Usage instructions
The data can be used in machine-learning applications such as GNN (https://github.com/igrega348/energy-equiv-lattice-gnn.git)
A library for interfacing with the data catalogues is available at https://github.com/igrega348/lattices.git
Please see README.html or README.md for detailed instructions.
