Poncelet penetration soil

Abstract A series of 80 penetration tests were performed to study the terminal depth of penetration into dry and saturated transparent synthetic sand. This review surveys knowledge about crater phenomena in the planetary science context, avoiding detailed descriptions already found in excellent papers on the subject. January 1, ; Issue published: Authors Authors and affiliations Yu. The threshold velocities for projectile penetration were Possible explanations for this difference are discussed. This article was invited by Sean Washburn.

Penetration of projectiles into granular targets - IOPscience

Statistical Mechanics for a Non-Conventional System. A LLDG consists of a laser level attached to a sliding scale with a digital readout. The precise measurements allow us to calculate Poncelet parameters for spheres in dry and saturated sand and fused quartz. There has been a flurry of recently funded research both in the U. That and the possible occurrence of projectile rebound, may account for I.
Predictions obtained using Eq. In this paper, a novel method known as photonic Doppler velocimetry PDV , capable of producing time resolved velocity measurements, is adapted for the study of objects penetrating rapidly into sand This is not in agreement with the results of Akers and Belmonte , who showed that when they plotted their normalised penetration depths versus the elastic Froude number Eq. Flexible - Read on multiple operating systems and devices. Results can be used to select a nose shape that can achieve the desired penetration depth. I did a Google search on "bullet penetration" and found, among others, these two calculators: April 11, ; Accepted:
