The aim of this thesis is to investigate how grain boundary (GB) strength and separation mechanisms affect strength and ductility of nanocrystalline materials. Such nanoscale …
This thesis presents experimental measurements and modeling of multi-scale collective behaviors characteristics of hierarchical interfaces in lithium-ion batteries (LIBs) during cycling. Two interfacial mechanisms are …
The nonlinear deformation response of two distinct materials was studied using finite element simulations. One is the hard Advanced High Strength Steels (AHSS) widely used …
Here we investigated the fracture and wrinkling in graphene with topological defects using atomistic simulations and continuum models. We first studied the flaw insensitive fracture …
A fundamental understanding of cell-nanomaterial interaction is essential for biomedical diagnostics, therapeutics, and nanotoxicity. Here we perform theoretical analysis to investigate the cellular uptake of …
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 …
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 …
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 …
A generalized thermoelastic model for adhesion was developed to elucidate the mechanism of dissipation within the viscoelastic bulk of a hydrogel. Results show that in …
Both interfaces and spatial gradients in engineering structures exhibit distinct mechanical properties in contrast to their bulk counterparts. The demands of both the aerospace and …
Developing high energy density battery systems has emerged as a major challenge in recent years. Silicon is considered to be a promising anode material for …
The surface morphologies of different soft material systems comprise various ruga phases (wrinkle, crease, fold or ridge). In the past a few decades, despite that …
The phase diagram of numerous materials of technological importance features high-symmetry high-temperature phases that exhibit phonon instabilities. Leading examples include shape-memory alloys, as well as …
The automobile industry drives a great deal of research towards understanding the mechanical behavior of high-strength steels. Two important behaviors exhibited by these materials are …
