Numerical Analysis of Penetration of Planetary Penetrator

2021 12th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2021
As a means of celestial body detection, high speed impact penetration detection has great scientific significance and research value. It can lay a key technical foundation for deep space exploration and space-based weapon system research in the future.

Controlling Penetration

SIAM Journal on Scientific and Statistical Computing, 1986
When particle methods are used to simulate the high Mach number collision of gas clouds particle streaming may occur because the particles can penetrate the interface between the clouds. We show how this penetration can be prevented by using an appropriate artificial viscosity. Numerical experiments in one and three dimensions are described.

Penetrance of Hemochromatosis

Blood Cells, Molecules, and Diseases, 2002
We undertook a three-year screening program for mutations of the HFE gene among 41,000 subjects attending the Kaiser Permanente Health Appraisal Center in San Diego, California. Our results show that the C282Y and H63D mutations of the HFE gene associated with hemochromatosis have measurable and consistent effects on iron indicators and are associated ...

Penetration enhancers

Advanced Drug Delivery Reviews, 2004
One long-standing approach for improving transdermal drug delivery uses penetration enhancers (also called sorption promoters or accelerants) which penetrate into skin to reversibly decrease the barrier resistance. Numerous compounds have been evaluated for penetration enhancing activity, including sulphoxides (such as dimethylsulphoxide, DMSO), Azones

Penetration performance of disk shaped penetrators

International Journal of Impact Engineering, 1992
Summary A combined computational, analytical and experimental investigation has discovered that there is a limit to the penetration efficiency of kinetic energy penetrators as the length-to-diameter ratio ( LID ) is decreased. Impacts of penetrators with an LID ranging from 1 to 1/32 into rolled homogeneous armor (RHA) at 2km/s were modelled with ...

Penetration mechanics of seg-tel penetrators

International Journal of Impact Engineering, 1997
Abstract Numerical simulations have been used to investigate the penetration performance of a segmented telescopic (seg-tel) penetrator between 1.6 and 2.5 km/s, with an emphasis at the higher impact velocities. Where applicable, the simulations are compared to experimental data. The simulations demonstrate that the penetration process of the seg-tel

Late-penetrating viruses

Current Opinion in Virology, 2011
Many enveloped and non-enveloped animal viruses delay the penetration into the cytosol of host cells until they have arrived to endocytic vacuoles deep in the cytoplasm. The late timing is generally determined by a low pH-threshold for the acid-activated penetration process (pH 6.2-4.9), but there can be a combination of other reasons for a delay ...
