Abstract
The penetration to geological shield occurs in many situations at various velocities and scales, for example, meteor-cratering, pile driving, falling of objects from high-rise building construction, and debris/fragments from failed components. The soil media is an efficient energy dissipation system and effective shock protection shield. Impact circumstances are currently getting widespread attention. A lot of research has been done on soil media for impact and penetration. The phenomenon of dynamic penetration in heterogeneous particulate soil medium is very complex and the target soil media under dynamic impact especially under high speed and deep penetration neither behave completely as solid nor as liquid. The topics of recent research interest in the field of penetration to soil media and their significant findings are critically reviewed in the present study. The dedicated review of analytical, empirical, experimental, and computational methods to predict the response of soils media-impacting objects to penetration is presented. The emerging challenges in fundamental research of penetration into soil media are outlined and it is an attempt to formulate the future research directions in the field of soil media penetration.
Highlights
Projectile penetration in soil media occurs in various circumstances at different velocities and scales, such as meteor-cratering [1], pile driving and dropping artifacts from high-rise building construction [2], debris/fragments from collapsed parts of construction [3], the digging of mining machineries [4], locomotion of legged robots over rough terrain [5], and raindrop impact to the soil surface [6]
Conducted penetration tests using “refractive index-matched granular media” with macroscopic physical and mechanical properties replicating the behavior of natural soils to visualize, non-intrusively, in-situ granular kinematics under impact penetration in granular media
It is established from the projectile–target interactions, understanding that the target soil media under dynamic impact, especially under high speed and deep penetration, neither behave completely as solid nor as liquid
Summary
Projectile penetration in soil media occurs in various circumstances at different velocities and scales, such as meteor-cratering [1], pile driving and dropping artifacts from high-rise building construction [2], debris/fragments from collapsed parts of construction [3], the digging of mining machineries [4], locomotion of legged robots over rough terrain [5], and raindrop impact to the soil surface [6]. A number of researcher have dedicated their work to study the process of projectile penetration into different material targets, such as for soil [15], rocks [16], concrete [17], glass [18] aluminum [19], steel [20], multi-layered fabric composite plates [21], high-density polyethylene honeycomb protection structure [22], and thermal protection material [23], among many other materials. An enormous number of studies on projectile penetration area have been published in last 50 years dealing with different process parameters such as different target materials, various geometry and velocity of impacting objects, and different investigation procedures. This review studies would provide updates on current and future research directions in the field of soil media penetration
