Скачать или смотреть Velocity plot: 50m asteroid impacted by 500kg hypervelocity penetrator

UCSB Deepspace – PI Project at www.deepspace.ucsb.edu/projects/pi-terminal-planetary-defense

ALE3D hydrodynamics simulation of a hypervelocity impact event between a 500 kg, 10:1 aspect ratio tungsten penetrator and a 50 m rubble pile asteroid. In the asteroid reference frame, the penetrator impacts at 20 km/s.

The asteroid is comprised of a spherical binder material with low strength (~ 25 Pa) and a distribution of spherical boulders with varying yield strengths (1 - 500 MPa) set inside.

Color scale shows the material velocity in centimeters per microsecond (1 cm/us = 10 km/s). Black outlines delineate boulders from binder material.

Note that the time between frames increases by a factor of 10 partway through the simulation.
