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...

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...
