The development of high-fidelity mechanical property prediction models for the design of polycrystalline materials relies on large volumes of microstructural feature data. Concurrently, at these same scales, the deformation fields that develop during mechanical loading can be highly heterogeneous. Spatially correlated measurements of 3D microstructure and the ensuing deformation fields at the micro-scale would provide highly valuable insight into the relationship between microstructure and macroscopic mechanical response. They would also provide direct validation for numerical simulations that can guide and speed up the design of new materials and microstructures. However, to date, such data have been rare. Here, a one-of-a-kind, multi-modal dataset is presented that combines recent state-of-the-art experimental developments in 3D tomography and high-resolution deformation field measurements.
用于多晶材料设计的高保真力学性能预测模型的开发依赖于大量微观结构特征数据。同时,在这些相同尺度下,机械加载过程中产生的变形场可能高度不均匀。对三维微观结构以及微观尺度下随之产生的变形场进行空间相关测量,将为微观结构与宏观力学响应之间的关系提供极具价值的见解。它们还将为数值模拟提供直接验证,从而指导并加速新型材料和微观结构的设计。然而,迄今为止,此类数据一直很稀少。在此,展示了一个独一无二的多模态数据集,该数据集结合了三维断层扫描和高分辨率变形场测量方面最新的先进实验进展。
