Modelling the Behavior of Dry and Saturated Crushable Granular Media Subjected to Varying Loading Rates

Description:

Granular materials are ubiquitous in nature and play a prominent role in countless technologies. The mechanical responses of multiphase granular material can vary significantly, when imposed to differential loading rates, depending on confinement, loading type and pore fluid properties. In this thesis, a versatile modelling platform is developed for delineating...

Deformation and Failure in Metallic Nanowires Under Stress-relaxation, Cyclic and High Strain Rate Loading Conditions

Description:

Metallic nanowires have become functional elements in many electronic devices such as the latest fin-FET (field effect transistor) from Intel, which has metallization layers with pitch as small as 90nm, flexible electronics, touch screens and nanoelectromechanical systems. This wide applicability of nanowires warrants extensive characterization of their fundamental properties such...
