Wallpaper Group-Based Mechanical Metamaterials
收藏资源简介:
该数据集名为“Wallpaper Group-Based Mechanical Metamaterials”,由埃因霍温理工大学的研究团队创建。数据集包含了1020种不同的二维微观结构及其在超弹性、有限应变范围内的宏观力学响应,包括屈曲现象。微观结构使用了一种新颖的方法生成,涵盖了所有17种墙纸对称群,并利用贝塞尔曲线提供了丰富的参数空间。力学响应通过基于有限元的计算均质化获得。该数据集支持代理模型的开发和基准测试,促进了对称性和特性关系的研究,并使对称性破缺过程中模式变换的研究成为可能,可能揭示机械超材料中涌现的行为。
This dataset, named "Wallpaper Group-Based Mechanical Metamaterials", was created by a research team at Eindhoven University of Technology. It contains 1020 distinct two-dimensional microstructures and their macroscopic mechanical responses within the superelastic finite strain range, including buckling phenomena. The microstructures were generated via a novel approach covering all 17 wallpaper symmetry groups, and leverage Bezier curves to provide a rich parameter space. The mechanical responses are obtained through finite element-based computational homogenization. This dataset supports the development and benchmarking of surrogate models, facilitates research on the relationship between symmetry and material properties, enables the study of pattern transformation during symmetry breaking processes, and may reveal emergent behaviors in mechanical metamaterials.
