Studies of two nanoscale systems with important engineering applications, Al-Si nanocomposites and Au nanoasperities, are investigated using molecular dynamics. The first system is studied in …
An experimental study of electric field induced surface diffusion is presented. A FEM analysis and a stability analysis of conducting surfaces subjected to a normal …
Nanometer-scale roughness on a solid surface has significant effects on friction, since inter-surface forces operate predominantly within a nanometer-scale gap distance in frictional contact. This …
An appealing approach to manufacturing future generation nanoscale devices envisioned for electronic, magnetic and photonic applications is to exploit the natural tendency of small material …
Solid-surface contact suspension is governed by asperity contact strength and multi-frequency surface roughness. Both of these two aspects are examined in this thesis for tribological …
Self-organization, in one of its accepted definitions, is the appearance of non-random structures in a system without explicit constraints from forces outside the system. In …
High-temperature, pressure-shear plate impact experiments were conducted in order to measure the plastic response of high-purity aluminum at high strain rates (106 s-1) and at …
The mechanics of biological contact are important in many natural processes, motivating extensive study of biological adhesive systems as well as attempts at biomimickry through …
When deformed at elevated temperature and slow strain rates, some Al alloys exhibits superplasticity, the ability to sustain very large tensile elongations (sometimes over 1000%) …
Cell-matrix adhesion depends on the collective behavior of a large number of molecular bonds. While the behavior of a single molecular bond is governed by …
