概要
- 論文の詳細を見る
The strength of component is strongly dependent on (1) material (atom species), (2) structure, and (3) loading condition. The theoretical strength, which is the ultimate strength of ideal crystal (structure), has been mainly investigated focusing on the factors (1) as a fundamental behavior of material. The small components, which are developed for advanced electronic devices and the elements of micro electro-mechanical system (MEMS), have their specific structure such as film, wire, dot etc. Then, it is required to investigate the theoretical strength of components with ideal atomic structure in order to understand the characteristic feature due to the factors (2) and (3). In this paper, we review our analytical results focusing on the factor (3). Moreover, the unstable criterion of arbitrary structure/material under arbitrary loading is discussed.
