چکیده
ABSTRACT In the process of underwater motion, trajectory projectile will be greatly disturbed due to complicated environment and cavitation effect. order study effect ice water mixture on experiments a titanium alloy slender body with truncated conical plat warhead passing through have been performed by using one-stage light gas gun loading system, an overpressure sensor measurement system high-speed camera acquisition in this paper. The experimental results show that volume cavity generated small length-to-diameter ratio is larger, deflects movement. For large ratio, formed closer central axis maximum radial size cavity. No matter shapes are or warhead, diameter lasting time increase body's velocities. Under condition velocity bodies similar, overall evolutionary trend two kinds similar. But fluctuation range amplitude small, curve oscillation adjacent peak value for large. same length diameter, has no obvious influence after hitting particles. When collides particles, deflection angle its larger than impacting edge interaction between particles large, impact.

Damage Assessment in Glass Fiber-Epoxy Matrix Composite under High Velocity Impact of Ice
This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...
متن کاملElectrical response of ammonium-rich water ice
The electrical properties of water ice impact the study of diverse frozen environments, in particular the radar sounding of ice masses. The high-frequency response of meteoric polar ice depends partly on the bulk concentration of ammonium (NH4 ), but the nature of this response has been unclear. Here we use broadband dielectric spectroscopy to investigate the electrical response of laboratoryfr...
