Drop-Liquid Impact Phenomena

2002
A brief survey of several phenomena occurring when a liquid drop impacts the surface of a pool of the same liquid is presented. The review touches upon drop oscillations, liquid-liquid contact, sound emission, bubble entrapment, and vorticity generation.

Hypervelocity-impact phenomena via molecular dynamics

Physical Review A, 1987
Novel molecular-dynamics calculations have been carried out for a hypervelocity impact of a sphere of 683 atoms (a central atom surrounded by 23 coordination shells) hitting a rectangular plate composed of 8000 atoms (five close-packed planes thick). The ratio of the sphere diameter to the plate thickness was chosen to be approximately 2.4, with the ...

Possible Impact Phenomena (PIPs)

2009
This chapter presents a catalog of documented events on the Moon likely (or possibly) resembling impact phenomena. These events are referred to by the author as possible impact phenomena (PIPs).The catalog was assembled from several different sources, listed later, and is divided into sections by century, beginning with the twelfth century.

Projectile Impact Phenomena and Existing Studies

2017
For the local response of the concrete target hit by a non-deformable projectile, three successive phenomenological responses are usually observed in test with the gradually increasing in the initial striking velocity V 0 of the projectile, as illustrated in Fig. 2.1.

Photoelastic phenomena in plastics during impact

Polymer Engineering & Science, 1962
AbstractThe study of strain patterns in deformed, transparent plastic placed between crossed Polaroids can shed considerable light on the responses of these plastics to stress. This article describes a study of the differing responses of three thermoplastics of varying degrees of toughness to the notched Izod impact test.

MeV-cluster impacts and related phenomena

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996
Point defect creation in 8.7 MeV C5-cluster irradiated LiF crystals have been studied in a dose range from 2 × 1010 up to 1 × 1013 C5+/cm2 and compared to the defect creation in similar conditions with single energetic carbon ions. An enhancement of the primary defect creation (F-centres) and aggregation (F2-centres) has been measured in a near surface

Phenomena resulting from hypervelocity impact

Journal of Spacecraft and Rockets, 1965
Crater damage to a thick plate via hypervelocity impact can be predicted from the tensile strength established by standard metallurgical techniques. Some of the results indicate that the frequently quoted empirical rule that the thickness of a plate that will just prevent penetration by a high-velocity particle is approximately 1.5 times the depth of ...
