Journal ArticleDOI
Review of experimental techniques for high rate deformation and shock studies
TL;DR: In this paper, a variety of techniques used to obtain the mechanical properties of materials at high rates of strain (⩾10 s−1) are summarised, including dropweight machines, split Hopkinson pressure bars, Taylor impact and shock loading by plate impact.
Journal ArticleDOI
Particle size effect on strength, failure and shock behavior in Polytetrafluoroethylene-Al-W granular composites
Eric B. Herbold,Vitali F. Nesterenko,David J. Benson,Jing Cai,Kenneth S. Vecchio,Fengchun Jiang,John Addiss,Stephen M. Walley,William G. Proud +8 more
TL;DR: In this paper, the authors performed quasi-static and dynamic experiments with identical constituent mass fractions with variations in the size of the tungsten (W) particles and pressing conditions and observed a higher ultimate compressive strength in relatively high porosity samples with small W particles compared to those with coarse W particles.
Journal ArticleDOI
Particle size effect on strength, failure, and shock behavior in polytetrafluoroethylene-Al-W granular composite materials
Eric B. Herbold,Vitali F. Nesterenko,David J. Benson,Jing Cai,Kenneth S. Vecchio,Fengchun Jiang,John Addiss,Stephen M. Walley,William G. Proud +8 more
TL;DR: In this article, the effect of particle size and sample porosity on the dynamic mechanical properties of high-density granular composite materials was investigated using a cold isostatically pressed mixture of polytetrafluoroethylene (PTFE), aluminum (Al), and tungsten (W) powders.
Journal ArticleDOI
Determination of physicomechanical properties of soft soils from medium to high strain rates
TL;DR: In this article, a method for obtaining materials parameters, for quartz sand, over a wide range of strain rates, involves the use of a modified Kolsky bar and plate impact experiments.
Journal ArticleDOI
High-strain, high-strain-rate flow and failure in PTFE/Al/W granular composites
TL;DR: In this paper, the Zerilli-Armstrong constitutive equation for polymeric solids was used to simulate the response of a PTFE/Al/W composite to high and high-strain conditions.
