Elastic properties of materials are fundamental physical properties that determine how materials respond to external stress and deformation . Accurately predicting these properties is critical for understanding the behavior of materials and their performance in various practical applications . Although the mechanical behavior of materials is influenced by microstructure, defects, and environmental conditions, single crystal models may offer valuable insights into their fundamental behavior, which can aid in the development of better materials. Nevertheless, the design of materials with exceptional elastic properties at an atomistic scale remains a persistent challenge in data-driven material discovery, given the vast chemical space and numerous possibilities available.
