概要
- 論文の詳細を見る
A two-dimensional amorphous structure of atoms interacting with a central force potential has been constructed and deformed in pure shear in a computer with a periodic boundary condition. The stress-strain relation has shown lower elastic moduli and much higher flow stress (0.04〜0.06μ_p) than the crystalline state. Elementary process of plastic deformation consists of chain-reacting collapses of holes (vacant spaces smaller than the ordinary vacancy) in the direction of the maximum shear line, which results in the slip nucleation and propagation in a macroscopic scale.
