Theory for atomic diffusion on fixed and deformable crystal lattices [PDF]

open access: yesarXiv, 1999
We develop a theoretical framework for the diffusion of a single unconstrained species of atoms on a crystal lattice that provides a generalization of the classical theories of atomic diffusion and diffusion-induced phase separation to account for ...

Fundamental study on seismic safety margin for seismic isolated structure using the laminated rubber bearings

open access: yesNihon Kikai Gakkai ronbunshu, 2021
This paper describes a fundamental study on the seismic safety margin for isolated structures using laminated rubber bearings. The variation of the seismic response assumed in the isolated structures will occur under the superposition of "Variations

Power law load dependence of atomic friction [PDF]

open access: yes, 2004
We present a theoretical study of the dynamics of a tip scanning a graphite surface as a function of the applied load. From the analysis of the lateral forces, we extract the friction force and the corrugation of the effective tip-surface interaction ...

Effect of KOH and dissolved hydrogen on oxide film and stress corrosion cracking susceptibility of Alloy X-750

open access: yesMechanical Engineering Journal, 2023
The replacement of LiOH with KOH for pH control in the primary water of pressurized water reactors (PWRs) is being considered due to the growing cost of enriched 7Li. This study aims to investigate the susceptibility of the primary water stress corrosion

Proposal for maintenance optimization scheme based on system based code concept

open access: yesMechanical Engineering Journal, 2023
To develop rationalized maintenance plans for nuclear power plants, the characteristics of each plant must be considered. For sodium-cooled fast reactor (SFR) plants, constraints on inspections exist due to the specialty that equipment retaining sodium ...
