Microstructural and mechanical characterization of variability in porous advanced ceramics using X-ray computed tomography and digital image correlation.
Download2019-01-01
Lo, Calvin, Sano, Tomoko, Hogan, James D.
This paper explores microstructural and mechanical variability in porous ceramics, combining advanced X-ray computed tomography (XCT) and digital image correlation (DIC) techniques to characterize an alumina material. The results show low variability in microstructure, with median pore size...

Microstructure evolution and infrared thermography applied to tensile failure of a dilatant polymeric foam
Download2021-11-01
Bhagavathula, K.B., Parcon, J.S., Azar, A., Ouellet, S., Satapathy, S., Dennison, C.R., Hogan, James D.
In this work, the authors study the thermo-mechanical response of a dilatant polymeric foam in quasistatic tension and compression, focusing on the links between microstructure, mechanical response, and associated temperature rises in these materials. The authors study these links for a...

Partially-observed microstructure models, containing stochastic volatility, dynamic trading noise and short term inertia, are introduced to address the following questions: (1) Do the observed prices exhibit statistically signicant inertia? (2) Is stochastic volatility (SV) still evident in the...

On the microstructure-dependency of mechanical properties and failure of low-pressure cold-sprayed tungsten carbide-nickel metal matrix composite coatings
Download2020-08-25
Munday, Guriqbal, Hogan, James D., McDonald, André
This study improves upon understanding of the effects of reinforcing particle content and microstructure on the mechanical properties and failure of low-pressure cold spray fabricated tungsten carbide-nickel (WC-Ni) metal matrix composite (MMC) coatings. Image analyses were performed on scanning...

Storytelling and Special Interests: Microstructure in the Fictional and Personal Narratives of Autistic Adults
DownloadSpring 2024
Background and objectives: Past research has found that autistic individuals have pragmatic and morphosyntactic deficits in narrative language; however, the majority of these studies use fictional narrative prompts and are on children, not older autistic individuals. Furthermore, very few use...

Zheng, Jie, Ji, Min, Zaiemyekeh, Zahara, Li, Haoyang, Hogan, James D.
This paper assessed the microstructure and properties of CeramTec ALOTEC 98 SB alumina ceramic through microscopic characterization and mechanical experiments. The rate-dependent strength and failure response of an alumina ceramic were studied under both uniaxial compression and compression-shear...

Studying the Microstructure of Electrodes for Low-temperature Solid Oxide Fuel Cell and Electrolysis Applications
DownloadFall 2022
Solid oxide fuel cells (SOFCs) is an important developing technology for energy conversion. This research was mainly focused on improving the fuel or air electrode of SOFCs in order to reduce the degradation rates and operation temperature. In chapters 3 and 4, a highly conductive...
