Hydroelastic Challenges for Wave-Impact Phenomena in Sloshing Flow

Volume 9: Odd M. Faltinsen Honoring Symposium on Marine Hydrodynamics, 2013
Depending on the local flow features before the impact, several and complex scenarios can characterize the physical evolutions of a wave impact in a sloshing flow. As a consequence, flip-through event or wave impact with gas-entrapment may happen causing localized and large loads. In all these cases, when the typical temporal duration of the local load

Impact ionization phenomena in AlGaAs/GaAs HEMTs

IEEE Transactions on Electron Devices, 1991
The impact ionization current in AlGaAs/GaAs high-electron-mobility-transistors (HEMTs) is evaluated by means of measurements of the gate current and high drain voltages. A previously reported method to calculate impact ionization coefficient in GaAs MESFETs is extended to HEMTs.

Electrical contact phenomena during impact

IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1991
The authors outline the theory of impact as it applies to electrical contacts. The concept of the coefficient of restitution is evaluated as a means of modeling the events at impact. The events occurring during the impact of electrical contacts are vital to the long-term reliability of the contacts; so design parameters are considered in terms of their

PARTICLE-SOLID IMPACT PHENOMENA

1962
Abstract : High velocity impact tests were made with high prity aluminum and copper projectiles and targets. Data are presented for impact velocities from 0.762 to 7.62 km/sec, and these are compared with various correlation formulas.

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.

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 ...

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.

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.
