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...

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...
