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...

Krimsky, Erez, Ramesh, K.T., Bratcher, M., Foster, M., Hogan, James D.
An understanding of the dynamic failure of damaged ceramics is important in protection applications, where the interaction of the projectile with cracked material is a contributing factor in the overall system performance. In this paper, we investigate the effects of pre-existing internal cracks...

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,...

Strain-Rate-Dependent mechanical behavior of a non-Equimolar CoCrFeMnNi high entropy alloy with a segmented coarse grain structure
Download2022-03-01
Li, Haoyan, Shao, Chenwei, Orhan, Okan K., Rojas, David Funes, Ponga, Maricio, Hogan, James D.
The mechanical response of a Co11.3Cr20.4Fe22.6Mn21.8Ni23.9 (wt%) high entropy alloy with a segmented coarse grain structure is investigated using strain-rate-dependent uniaxial compression experiments. The composition is verified using ab-initio simulations by examining thermal stability through...
