On the study of ricochet and penetration in sand, water and gelatin by spheres, 7.62 mm APM2, and 25?mm projectiles
(2016)
We examine the ricochet and penetration behavior in sand, water and gelatin by steel spheres, 7.62 mm APM2 and 25 mm projectiles. A threshold impact angle (critical angle) exists beyond which ricochet cannot occur. The ...
Experimental and numerical study of the fragmentation of expanding warhead casings by using different numerical codes and solution techniques
(2014)
There has been increasing interest in numerical simulations of fragmentation of expanding warheads in 3D. Accordingly there is a pressure on developers of leading commercial codes, such as LS-DYNA, AUTODYN and IMPETUS Afea, ...
Strain rate dependency and fragmentation pattern of expanding warheads
(2014-12-22)
For the characterization of the behaviors of a metal material in events like expanding warheads, it is necessary to know its strength and
ductility at high strain rates, around 104
