More Book Details

Description of the Book:

Computer-based large-scale molecule dynamics simulations are developed, implemented and used to investigate the energetics and dynamical mechanisms in materials under stress and interfacial processes occuring between material tips and substrate surfaces. Studies of the consequences of intermetallic interactions between a nickle tip and a golf surface reveal microscopic information about processes of adhesion, contact formation, nanoindentation, connective neck formation, plastic deformation and fracture. The theoretical predictions correlate well with Atomic force microscopy experiments. Novel tribological phenomena coupled to enhanced surface superionic conductivity in (Cadmium Fluoride) are investigated. Keywords: Tribological processes, Nanomechanics, Molecular dynamics simulations of tip-substrate interactions, Atomic force microscopy, Mechanics, Surface chemistry, Materials
