An experimental study on the strain-rate-dependent compressive and tensile response of an alumina ceramic
Download2022-10-01
Ji, Min, Li, Haoyang, Zheng, Jie, Yang, Shuo, Zaiemyekeh, Zahra, Hogan, James D.
This research article studied the strain-rate-dependent mechanical response of a CeramTec Alotec 98% alumina ceramic under uniaxial compression and indirect tension loadings. Mechanical testing was carried out using a load frame for quasi-static strain rates and a split-Hopkinson Pressure Bar...

Li, H.Y., Motamedi, P., Hogan, James D.
This study investigates the micro/nanostructural features and mechanical responses of a novel TiAl/Ti3Al/Al2O3 cermet fabricated by self-propagation high-temperature synthesis. The microscopic diagnosis was used to examine the material composition, phase distribution, and elemental concentration...

Development of Microstructure-Informed Computational Models for the Design of Cold-Sprayed Additively Manufactured Metal-Ceramic Composite Materials
DownloadFall 2024
This thesis develops microstructure-based finite element (FE) models of cold-sprayed additively manufactured (CSAM) metal-ceramic composites – Al-Al2O3 in this research – to fill a gap in our understanding of the microscale failure progression in the material in correlation with its macroscale...

Micro-hardness and strain-rate-dependent compressive response of an ultra-light-weight Mg-Li-Al alloy
Download2022-01-15
Li, Haoyang, Shao, Chenwei, Rojas, David Funes, Ponga, Mauricio, Hogan, James D.
A study on the microstructure and composition, micro-hardness and strain-rate-dependent compressive behaviors, and the associated failure mechanisms of an ultra-light-weight Mg-Li-Al alloy were conducted. X-ray diffraction and X-ray photoelectron spectroscopy showed a multi-phase material with...

On the Rate-dependency of Mechanical Properties and Failure Mechanisms of a (γ + α2) - TiAl/Ti3Al-Al2O3 Cermet
Download2020-07-01
Li, Haoyang, Motamedi, Pouyan, Hogan, James D.
This study investigated the rate-dependent mechanical properties and failure of a self-propagating high-temperature synthesized TiAl/Ti3Al-Al2O3 cermet using mechanical testing and advanced microscopy. Quasi-static and dynamic uniaxial compression tests coupled with high-speed imaging and digital...

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...
