Cooperative atomic motion during shear deformation in metallic glass
Yoshinori Shiihara, Takuya Iwashita, Nozomu Adachi +2
Elucidating mechanical deformation in glassy materials at the atomic level is challenging due to their disordered atomic structure. Using our novel "frozen atom analysis," we revea…
Local stress analysis in CuZr metallic glass under shear strain by means of first principle modeling
I. Lobzenko, Y. Shiihara, T. Iwashita
Metallic glasses deform elastically under stress. However, the atomic-level origin of elastic properties of metallic glasses remain unclear. In this paper using {\em ab initio} mol…
Elementary excitations and crossover phenomenon in liquids
T. Iwashita, D. M. Nicholson, T. Egami
The elementary excitations of vibration in solids are phonons. But in liquids phonons are extremely short-lived and marginalized. In this letter through classical and ab-initio mol…
Atomic Mechanism of Flow in Simple Liquids under Shear
Takuya Iwashita, Takeshi Egami
Atomic correlations in a simple liquid in steady-state flow under shear stress were studied by molecular dynamics simulation. The local atomic level strain was determined through t…
