A Study on the Strain-Rate- and Stress-State-Dependent Behavior of Advanced Ceramics: Experimental Mechanics and Multiscale Simulations
DownloadFall 2024
Design and development of better-performing ceramic structures are vital in industry-driven applications where a wide range of strain rates and stress states are induced in the material (e.g., impact events). Accordingly, this thesis investigates the strain-rate and stress-state-dependent...

Confined Uniaxial Compaction Observing Triaxial Response of Granular Media under Quasi-static Loading Conditions
DownloadFall 2019
Experimental studies have been carried out in this thesis to enhance the understanding of granular material failure by observing the effects of particle size on material properties. Understanding the granular behaviour of materials is important in pharmaceutical research, product quality in the...

Data-driven approaches to defining material property and performance relationships of armor ceramics undergoing dynamic loading
DownloadSpring 2023
This thesis utilizes a combined numerical and machine learning approach to explorethe performance of an alumina ceramic tile undergoing high-velocity impact. The fi-nite element model is established by incorporating a user-defined Johnson-Holmquist-Beissel (JHB) material model within the...

Effects of Oxide Additions on the Corrosion Behaviour of Cr2O3 Based Ceramics in High Temperature Supercritical Water Environment
DownloadFall 2012
This investigation is aimed at developing ceramic materials applied in supercritical water, which is being considered as coolant for one of the next generation nuclear reactors. Cr2O3, a primary protective film on stainless steels, was found to be unstable in SCW due to the formation of soluble...
