Phononic crystals are periodic, composite solids that exhibit phononic band gaps – frequency ranges in which elastic waves are prohibited. When made from soft elastomers, …
Two-dimensional (2D) materials exhibit ultra-high strength due to their nearly perfect lattice structures but low fracture toughness due to their lack of effective energy dissipation …
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 …
In 1959, physicist Richard Feynman gave a historical lecture: `There's Plenty of Room at the Bottom'. Even after sixty years, the exciting field of nanotechnology …
The work presented here describes two major problems: 1) Structural evolution of graphene oxide layers during thermal reduction using combined numerical methods and experimental measurements, …
The mechanical interaction between cells and their microenvironments is a significant factor affecting biological and physiological processes. Cell-matrix interactions have historically been measured by computing …
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 …
In nanocrystalline materials it is well postulated that the grain boundary phenomena such as dislocation emission/annihilation, partial nucleation, grain-boundary (GB) sliding, and GB diffusion dominate …
Through coarse grained molecular dynamics (CGMD) simulations and theoretical models, we show that, depending on the radius, a carbon nanotube can enter a cell either …
Generation of forces is essential for the migration of neutrophils to the sites of infection or injury. The mechanical properties and local confinement of the …
Novel applications of materials in small dimensions are emerging in areas ranging from electronics, computers, health technologies, laser and fiber optics, to energy harvesting and …
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 …
Compatibility conditions for various strain measures are well known in both small and finite strain kinematics. For many plane deformation problems in solid mechanics, such …
This thesis presents the applications of phase field modeling in fracture analysis. In this method, a diffusive crack zone controlled by a scalar auxiliary variable …
The spontaneous growth of long, filamentary whiskers from the surface of Sn-plated Cu conductors poses a serious threat to the reliability of electronic components. While …
Metallic alloys including high strength steels, refractory alloys, metallic glasses, and high entropy alloys have attracted great research interests in the past decade due to …
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%) …
Granular materials are ubiquitous in nature and indispensable in industry, and it is essential to be able to model granular materials from a continuum perspective …
