Farbaniec, Lukasz, Hogan, James D., McCauley, James W., Ramesh, Kaliat T.
Effects of microstructure and material properties on the mechanical behavior of hot-pressed boron carbide are presented. The microstructure and intrinsic microstructural inhomogeneities have been characterized using scanning electron microscopy characterization techniques (SEM/EDS/EBSD). In-situ...

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...

The dynamic response of hot-pressed boron carbide was studied under uniaxial and confined loading conditions using a modified compression Kolsky bar setup at strain rates of 102 – 103 s–1. The progression of damage in the prismatic specimens was captured using a high-speed camera. This...

In this paper, the impact-induced fragmentation of a commercially available hot-pressed boron carbide is explored. Fragmentation has been noted previously by many authors to be important in the impact performance of advanced ceramics, and so this paper seeks to provide some of the first...

Farid, Hannaneh Manafi, McDonald, André, Hogan, James David
This study explores the role of porosity in the impact deposition of a ceramic-reinforced metal-matrix (i.e., Al/B4 C) composite coating fabricated via cold spraying. The Johnson–Holmquist–Beissel constitutive law and the modified Gurson–Tvergaard–Needleman model were used to describe the high...

Micromechanisms Associated with the Dynamic Compressive Failure of Hot-Pressed Boron Carbide
Download2015
Ramesh, K.T., Farbaniec, Lukasz, Hogan, James
Brittle failure in boron carbide has been studied in dynamic uniaxial compression using a Kolsky bar technique. A detailed study of fragments was performed using SEM-EDS, to identify the mechanisms responsible for failure. Microstructural characterization and fracture surface observations...

On the evaluation of mechanical properties and ballistic performance of two variants of boron carbide
Download2021-06-01
Lo, Calvin, Li, Haoyang, Toussaint, Geneviève, Hogan, James D.
A comparative study on the microstructure, rate-dependent compressive behavior, and ballistic performance of commercially available pressureless sintered boron carbide-titanium diboride (material Z) and hot-pressed boron carbide (material S) was conducted. Under quasi-static compression at rates...

Quasi-static confined uniaxial compaction of granular alumina and boron carbide observing the particle size effects
Download2019-10-25
Nicewicz, Piotr, Peciar, Peter, Macho, Oliver, Sano, Tomoko, Hogan, James D.
The quasi-static confined uniaxial compaction of granular alumina and boron carbide was studied, and the effect of triaxial stress on the materials as a function of increasing particle size was observed. The average particle sizes studied for granular alumina were 170 ± 63, 230 ± 55, 330 ± 67,...
