Development of Criterion for Mechanical and Functional Fractures in Nano-Structures

在这项研究中，我开发的标准来描述机械断裂以及原子组件的功能不稳定性。通过将该方法应用于铁电和磁性系统，验证了该方法的有效性。此外，该方法描述了原子组件中的断裂和功能不稳定性的起源。进一步阐明了纳米结构材料的多物理特性（机械变形与功能性的耦合效应）。

In this study, I developed the criterion to describe the mechanical factures as well as functional instabilities of atomic components. We validated the proposed method as criterion by applying the method to ferroelectric and magnetic systems. In addition, the method describes the origin of fractures and functional instabilities in the atomic components. I further elucidated the multi-physics properties (the coupling effect between mechanical deformation and functionalities) in nano-structured materials.
