Limit Impact Velocity of Frangible Bullet
2019 International Conference on Military Technologies (ICMT), 2019The article deals with the determination of a limit impact velocity of a frangible bullet. Limit impact velocity is the lower limit impact velocity of the bullet on the hard target, at which the bullet begins to shatter into the fragments. The limit impact velocity of the bullet is one of the criteria to evaluate the frangibility of the frangible ...

Damage threshold velocities for liquid impact
Journal of Materials Science, 2000Rain erosion is a major cause of strength and transmission loss in IR ‘windows’ in high velocity flight. The Cavendish Laboratory's Multiple Impact Jet Apparatus (MIJA) is able to simulate high velocity rain impact accurately and reproducibly under laboratory conditions using a series of discrete water jets.

Mass-Velocity Correlation in Impact Fragmentation
Key Engineering Materials, 2013We study the impact fragmentation of two-and three-dimensional disordered solids in a discrete element model of heterogeneous brittle materials focusing on the spatial distribution and mass-velocity correlation of fragments. Our calculations revealed that depending on the energy of impact the breakup process can have two different outcomes: at low ...

HYPERVELOCITY IMPACT: DEPENDENCE OF CRATER DIMENSIONS ON IMPACT VELOCITY
1965Abstract : Craters in copper and lead, produced by hypervelocity impact, have been measured and the dimensions correlated with impact velocity. The results indicate that craters scale with about the 1.7 power of velocity, in agreement with computer physics results based upon hydrodynamic calculations.

Spallation Resulting from High-Velocity Impacts
1979A high-velocity projectile impact generally creates a crater in the target, driving a strong shock wave into the material. If the target is sufficiently thin, a puncture will result. If the target is relatively thick, the shock wave will rapidly decay into a spherical elastic stress wave.

Greening Big Data Networks: Velocity Impact
2018The authors investigate the impact of big data's velocity on greening IP over WDM networks. They classify the processing velocity of big data into two modes: expedited-data and relaxed-data modes. Expedited-data demands higher amount of computational resources to reduce the execution time compared with the relaxed-data.
