Multiscale Modeling and Applications in Nanotribology
A concurrent multiscale modeling approach to scaling up amorphous materials using Pseudo Amorphous Cell (PAC) is proposed. This approach is derived in detail for 2D case. It is then validated by performing multiscale simulation of nanoindentation on a 2D polymer substrate. A good agreement between …

High Speed Atomic Force Microscopy Techniques for the Efficient Study of Nanotribology
… understand friction and wear at the nanoscale (nanotribology) especially at technically relevant sliding velocities. Accordingly, three novel techniques have been developed to study nanotribology, leveraging recent advances in high speed AFM. The first method utilizes high line-scanning rates …

Nanotribology and Nanomechanics Including Nanomechanical Properties, Adhesion and Surface Roughness With Application to Magnetic Storage Hard Disk Drives
In the second part of this work, a systematic approach considering the above basic elements was used to investigate impact-induced contact damage of Head Disk Interfaces during operational shock. A contact mechanics based analysis with consideration of mechanical properties and thickness of various …

Dynamics of sliding mechanisms in nanoscale friction
Nanotribology is the study of friction and wear at the nanoscale, with relevance to such applications as micromechanical systems (MEMS) and thin, hard coatings. For these systems, classical laws of friction are inappropriate due to the small dimensions of the sliding elements and the lack of …

Nanoscale Investigation of Adhesion, Friction, and Wear in Chemically Heterogeneous Responsive Polymer Brushes
Polymer brushes provide the responsive smart surfaces which can be used for fabrication of various devices. In this thesis work, adhesion, friction, and wear of polystyrene (PS) - poly(2-vinyl pyridine) (P2VP) and polystyrene - poly(acrylic acid) (PAA) binary brushes and corresponding monobrushes …

Softmatter tribology: Understanding the microstructure to property relationships of hydrogel-like materials
… behavior of hydrogel thin films in tandem with nanotribology was conducted to show that the effective viscosity measured in rheology agrees with the friction behavior, although it is not sufficient to capture the rich frictional response of hydrogels as a function of sliding velocity. In the …

Multiscale Mechanics of Graphene Oxide and Graphene Based Composite Films
The mechanical behavior of graphene oxide is length scale dependent: orders of magnitude different between the bulk forms and monolayer counterparts. Understanding the underlying mechanisms plays a significant role in their versatile application. A systematic multiscale mechanical study from …
