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...

Smart Textiles for Visible and IR Camouflage Application: State-of-the-Art and Microfabrication Path Forward
Download2021-06-30
Degenstein, Lauren M., Sameoto, Dan, Hogan, James D., Asad, Asad, Dolez, Patricia I.
Protective textiles used for military applications must fulfill a variety of functional requirements, including durability, resistance to environmental conditions and ballistic threats, all while being comfortable and lightweight. In addition, these textiles must provide camouflage and...

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...

Thermodynamically-consistent derivation and computation of twinning and fracture in brittle materials by means of phase-field approaches in the finite element method
Download2022-10-01
Amirian, Benhour, Jafarzadeh, Hossein, Abali, Bilen Emek, Reali, Alessandro, Hogan, James D.
A theoretical-computational framework is proposed for predicting the failure behavior of two anisotropic brittle materials, namely, single crystal magnesium and boron carbide. Constitutive equations are derived, in both small and large deformations, by using thermodynamics in order to establish a...

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...

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...

Amirian, Benhour, Jafarzadeh, Hossein, Abali, Bilen Emek, Reali, Alessandro, Hogan, James D.
Crack initiation and propagation as well as abrupt occurrence of twinning are challenging fracture problems where the transient phase-field approach is proven to be useful. Early-stage twinning growth and interactions are in focus herein for a magnesium single crystal at the nanometer...

Shao, Chenwei, Li, Haoyang, Zhu, Yankun, Li, Peng, Yu, Haoyang, Zhang, Zhefeng, Gleiter, Herbert, McDonald, André, Hogan, James D.
Nanostructured materials are being actively developed, while it remains an open question how to rapidly scale them up to bulk engineering materials for broad industrial applications. This study propose an industrial approach to rapidly fabricate high-strength large-size nanostructured metal...
