It was observed that, during spudcan penetration, the development of sand plug trapped beneath the spudcan played a crucial role in the bottom boundary effect. The boundary effect started earlier when the ratio of sand layer thickness to spudcan diameter was greater than ://

Investigations of the projectile penetration phenomenon in granular soils have been impeded by the difficulty in adequately quantifying and characterizing soil targets, and by the inability to directly scale results of 1-g penetration tests to full-scale conditions.
The former is largely due to the failure to adequately prepare and quantify laboratory test samples, and the inherent limitations T/abstract. Results from centrifuge and 1‐g model tests of projectile penetration into granular soils are described. Solid spherical projectiles in four calibers were fired into uniform samples of dry sand at approximately m/s.
Comparison to full‐scale test results verified the suitability of the centrifuge testing technique for this type of ://(ASCE)()(). This paper describes the rationale for using centrifuge modeling for projectile penetration studies in granular soils and presents details of a projectile delivery system that has been used to conduct centrifuge penetration tests.
Included in the rationale is a dimensional analysis that indicates that self-weight induced stresses in the The study results showed that centrifuge modeling is an appropriate and powerful tool for investigating projectile penetration in granular soil.
Both centrifuge and 1-g data fit well withing bounds predicted by Young's equation. As in Young's full-scale tests, penetration depth is seen to be strongly dependent on the projectile mass-to-area :// This chapter is concerned with kinetic energy driven penetration into soils and soil-like granular materials.

Introduction. There has been a recent surge of interest in penetration of granular materials. Impact and penetration into granular media is important for many engineering applications, including subsurface investigations, planetary impact, and offshore foundations and anchors, among aspects of penetration mechanics have been addressed in recent :// The equation has the form where, and are positive constants and denotes the projectile penetration velocity at time.

A series of 80 penetration tests were performed to study the terminal depth of penetration into dry and saturated transparent synthetic sand. The transparent sand was made by matching the refractive index of granulated fused quartz with a pore fluid made of either sucrose or mineral oil.
Tests were conducted by shooting spherical projectiles at speeds of up to m/s into the transparent soil Centrifuge modeling of projectile penetration in granular soils zy, & Etude en centrifuge use de I 'impact de gros blocs rocheux sur un remblai de protection Centrifuge modeling of the impact of large blocks of rock on a protection earthfill (Summary) P Lepert & Zlatovic S., Ishihara K.: Normalized behavior of very loose non-plastic soils: effects of fabric.
