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...

Zaiemyekeh, Zahra, Li, Haoyang, Sayahlatifi, Saman, Ji, Min, Zheng, Jie, Romanyk, Dan L., Hogan, James D.
This study investigates the stress-state- and strain-rate-dependent behavior of CeramTec ALOTEC 98% alumina (Al2O3) ceramic through experimentally validated finite element (FE) modeling. As the constitutive material model, a rate-dependent viscosity-regularized phenomenological model (JH2-V...

Experimental Studies and Multi-Scale Modelling of Advanced Ceramics: Fracture, Fragmentation, and Failure
DownloadFall 2024
The objectives of this thesis is to explores the mechanical behaviour of alumina ceramics, focusing on fracture and fragmentation response through a blend of experimental investigations and advanced computational modelling. To bridge the gap between micro-mechanisms and macroscopic material...

Exploring international student mobility: neoliberal globalization, higher education policies and Chinese graduate student perspectives on pursuing higher education in Canada
DownloadSpring 2010
With the advent of neoliberal globalization in the 1980s, international student mobility (ISM) has become a significant social and educational phenomenon. Given the increasing magnitude of international student flows from “developing countries” to the “developed” or major member countries of the...

Hybrid Finite-Discrete Element Modeling of the Mode I Tensile Response of an Alumina Ceramic
Download2023-03-13
Zheng, Jie, Li, Haoyang, Hogan, James D.
We have developed a three-dimensional hybrid finite-discrete element model to investigate the mode I tensile opening failure of alumina ceramic. This model implicitly considers the flaw system in the material and explicitly shows the macroscopic failure patterns. A single main crack perpendicular...

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...

Zheng, Jie, Li, Haoyang, Hogan, James D.
The strain-rate-dependent tensile response of a commercial alumina ceramic (CeramTec 98% alumina) is investigated by experimental and modeling methods. The experiments at different loading rates are carried out on a standard MTS machine and a modified split-Hopkinson pressure bar system with...
