Substrate Effect, Pile-Up and Sink-In Factors During Thin Film Nanoindentation

Schwieker, Kevin (2011-08-19)

Theoretical and experimental models continue to be developed for thin-film nanoindentation that attempt to account for substrate effects in differing film-substrate combinations. While many models have been developed to ...

Surface Separation and Contact Resistance Considering Sinusoidal Elastic-Plastic Multiscale Rough Surface Contact

Wilson, William (2008-12-15)

This thesis considers the multiscale nature of surface roughness in a new model that predicts the real area of contact and surface separation as functions of load. This work is based upon a previous rough surface multiscale ...

Terrain Characterization and Roughness Estimation for Simulation and Control of Unmanned Ground Vehicles

Dawkins, Jeremy (2011-12-02)

This dissertation presents a methodology for generating artificial terrains for simulation of off-road vehicles. Furthermore it develops and evaluates methods for characterizing the terrain for the control of unmanned ...

Theoretical and Experimental Analysis of Strain in a Tire Under Static Loading and Steady-State Free-Rolling Conditions

Krithivasan, Vijaykumar (2011-04-11)

This main objective of this work is to predict the operating conditions or the state of a tire based on a wireless sensor suit. First a three dimensional finite element model of a standard reference test tire (SRTT) was ...

The Tribological and Electrical Effects of Nanoparticle and Proprietary Lubricants

Crilly, Larkin (2021-04-12)

Electrical systems of any type rely upon electrical connectors or contacts; these may be found in places like computers, light switches, or electric vehicles and are present in a wide range of environments as a result. ...

Understanding Effects of Tapering Cantilevered Piezoelectric Bimorphs for Energy Harvesting from Vibrations

Siddiqui, Naved (2014-12-09)

Piezoelectric energy harvesting from vibrations is a field that has gathered much attention over the past decade. The purpose of this application is to realize ambient sources of kinetic energy such as vibrations, and turn ...

Use of Surface Specific Flow Factors in a Multi-Physical Model of Power Cylinder Components

Locker IV, Alex (2018-04-23)

New technologies are being introduced for power cylinder components at a faster rate due to the drive for better fuel economy and CO2 foot print reduction. This includes new and advanced coatings, materials, and surface ...

Wear Simulation of Electrical Contacts Subjected to Vibrations

Shinde, Darshan (2008-08-15)

Electrical contacts may be subjected to wear because of shock, vibration, and thermo-mechanical stresses resulting in fretting, increase in contact resistance, and eventual failure over the lifetime of the product. Previously, ...
