Thresholds of Axial Vibration Induced Fretting Corrosion in Electrical Connectors
(2013-04-22)
Vibration induced fretting corrosion has been considered an important cause of failure in electrical contacts. In previous research, the basic mechanism that controls the inchoation and development of such fretting degradation ...
Effects of Grain Size and Orientation on Mechanical Response of Lead Free Solders
(2013-11-25)
In this study, the effects of grain size and orientation on mechanical behaviors of lead free solders were evaluated by measuring the sub-grain size and determining the plane orientation of the grains. Sn-Ag-Cu (SAC) solder ...
Development and Testing of Innovative Instructional Materials to Improve Student Learning in Engineering Classes - Case Studies, Smart Scenarios and Serious Games
(2013-08-21)
Most mechanical engineering courses require students to work on over-simplified theoretical representations of real-world problems. Although this gives students an in-depth understanding of concepts and principles, they ...
Development of a test procedure to study the effect of unilateral load on the posture and trunk biomechanics during walking (Gait) using nonlinear methods
(2013-08-21)
Low back pain is a common musculoskeletal disorder that affects 80 percentages of people at some point in their lives. In the United States it is the most common cause of job-related disability, a leading contributor to ...
Material Characterization of Leadfree SAC Solder Alloys at High Strain Rates with Finite Element Analysis
(2013-07-25)
The electronics may experience high strain rates under single, sequential and simultaneous exposure to thermo-mechanical and transient dynamics loads at various stages of their life-cycle i.e. manufacturing, transportation, ...
A Constitutive Model for Lead Free Solder Including Aging Effects and Its Application to Microelectronic Packaging
(2013-08-01)
The microstructure, mechanical response, and failure behavior of lead free solder joints in electronic assemblies are constantly evolving when exposed to isothermal aging and/or thermal cycling environments. Traditional ...
Investigation of Thermally-Actuated Pumping During Pool Boiling of a Dielectric Liquid on an Asymmetric Microstructured Silicon Heat Sink
(2013-08-20)
Developments in the field of electronics fabrication have led to significant miniaturization of devices. Such a reduction in foot-print of the electronic devices coupled with increased capabilities, such as computing ...
Numerical Investigation of the Solidification of Nanoparticle-Based Colloidal Suspensions
(2013-07-29)
In this dissertation, analytical and numerical approaches were used for analysis of the solidification process of nanoparticle-based colloidal suspensions, with a special emphasis to those used as nanostructured-enhanced ...
Ultra-wideband Radio Aided Carrier Phase Ambiguity Resolution in Real-Time Kinematic GPS Relative Positioning
(2013-07-10)
In this thesis, ultra-wideband radios (UWBs) are integrated into the real-time kinematic (RTK) algorithm using differential GPS techniques to achieve a highly precise relative positioning vector between GPS antennas. This ...
Three-Dimensional Modeling of Elasto-Plastic Sinusoidal Contact under Time Dependent Deformation Including Both Stress Relaxation and Creep Analysis
(2013-07-11)
Computational modeling of contact between rough surfaces has attracted a great deal of attention due to the developing technological needs of industry. Most of the early models of rough surface contacts assumed a cylindrical ...
