Abstract Scope |
Structural materials play a vital role in ensuring the safety of various systems, from civil to military applications. Failure of these materials can lead to catastrophic consequences, necessitating their reliable and predictable performance under all loading scenarios. This study focuses on damage initiation in incipient spall experiments, where grain boundaries (GBs) have been observed as preferential sites for void nucleation. In this research, we train neural networks to identify voids in microstructures. The datasets are constructed using both available properties from EBSD analysis and surrogate models. Notably, GB energy is computed using the lattice-matching method and retroactively used to estimate the boundary's out-of-plane inclination. By amalgamating physical and geometric properties, our model uncovers subtle trends contributing to void nucleation. This study presents the dataset processing, assembly, and training results of the framework, which will ultimately facilitate rapid screening and design of damage-resistant microstructures for enhanced safety in structural materials. |
