Fracture toughness of void-site-filled skutterudites

Creator:: Eilertsen, James S.
Abstract:: Thermoelectric materials are playing an increasingly significant role in the global effort to develop sustainable energy technologies. Consequently, the demand for materials with greater thermoelectric efficiency has stimulated the development of state-of-the-art interstitially doped skutterudite-based materials. However, since intermetallics are often embrittled by interstitial substitution, optimal skutterudite-based device design, manufacture,...

The Effect of Isothermal Aging on the Development of Long-Range Order in Ni-based Alloys

Creator:: Aerne, Nicholas S. J.
Abstract:: Nickel (Ni)-based alloys with a high chromium (Cr) content are frequently employed in applications where elevated temperatures and/or corrosive environments are present due to their excellent corrosion resistance and mechanical properties. However, a gap exists around the formation, and kinetics of long-range order (LRO) Ni2Cr phase in both model binary...

Adhesive Properties Subject to Variation in Temperature, Thickness, and Working Time

Creator:: Aerne, Nicholas, S. J.
Abstract:: Adhesive use is becoming increasingly common in manufacturing processes. The advantage of adhesives are light weight components, non-destructive fastening techniques and distribution of loads over the applied bond region. Modeling the behavior of adhesive bond lines in fastening joints can help in the design process to make an optimized joint,...

Distortion-induced fatigue cracking of girder-to-crossbeam connection

Creator:: Aljutaili, Dhari S.
Abstract:: Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...

Optimization of staged rankine energy conversion cycles for high efficiency

Creator:: Simmons, Larry Dean
Abstract:: Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...

Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

Creator:: Walker, Anthony S.
Abstract:: Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...
