Abstract
The formation of cavities in firm soil by penetration of one-piece or segmented metallic penetrators moving with a velocity of 3–5 km/s is numerically simulated in terms of the two-dimensional axisymmetric problem of continuum mechanics. It is shown that the cavity can be made more than twice as deep by segmenting an elongated one-piece penetrator. The increment of the penetration depth as a function of the number of segments and segment spacing along the direction of motion is studied.
