Database of 120,000 reaction-diffusion-generated architected material structures and their effective mechanical properties

This database contains 120,000 reaction-diffusion-generated architected material structures together with the corresponding reaction-diffusion parameters and computed effective mechanical properties. Each structure is represented as a binary two-dimensional matrix corresponding to a representative volume element (RVE) model with periodic boundary conditions, where 1 denotes the material phase and 0 denotes the void phase. For every structure, the database provides: • Reaction-diffusion parameters (Da, Db, f, k) • Binary structural representation • Effective elastic properties (Ex/Em, Ey/Em, Gxy/Gm, Emean/Em) • Effective Poisson's ratios (νxy, νyx, νmean) The database accompanies the article: “Beyond unit cells: programmable morphogenetic design of irregular architected materials” The repository includes the complete database in HDF5 format, metadata describing all variables, checksum files for integrity verification, and example Python code for reading the data.本数据库包含120000个由反应-扩散生成的架构型材料结构，以及与之对应的反应-扩散参数与计算得到的有效力学性能。 每一个结构均以二进制二维矩阵形式呈现，对应带有周期性边界条件的代表性体积单元（Representative Volume Element, RVE）模型，其中1代表材料相，0代表孔隙相。 针对每一个结构，本数据库提供以下内容： • 反应-扩散参数（Da、Db、f、k） • 二进制结构表征 • 有效弹性性能（Ex/Em、Ey/Em、Gxy/Gm、Emean/Em） • 有效泊松比（νxy、νyx、νmean） 本数据库配套发表于论文："Beyond unit cells: programmable morphogenetic design of irregular architected materials" 该存储库包含完整的HDF5格式数据库、描述所有变量的元数据、用于完整性验证的校验和文件，以及用于读取数据的示例Python代码。
