Notes on photoelasticity of impact phenomena
International Journal of Mechanical Sciences, 1983Abstract Attenuation and interference of stress waves affect fringe propagation velocities and produce transitory sources and sinks of dynamic fringes. A simplified wave model serves to explain the basic phenomena involved. Striker impacts also create quasi-static fringes which are distinguishable within the dynamic pattern and may lead to an ...

HYPERVELOCITY IMPACT PHENOMENA
1963Abstract : A summation of the research performed at the Explosives Research Laboratory, Pittsburgh, Pa. in the field of hypervelocity impact on thin targets is presented. The immediate goal of the research is to obtain a complete description of the thin-plate perforation process within the limits of available explosive projectors.

The scaling of impact phenomena
International Journal of Impact Engineering, 1987Abstract A basis for scaling laws for impact phenomena is the approximation of the actual problem with a point-source problem. Point-source solutions are characterized by a single scalar coupling-parameter measure aU μδυ of the radius a , velocity U and mass density δ of the impactor.

Impact Phenomena at High Speeds
Journal of Applied Physics, 1956A study of high speed, metal-to-metal impact in the velocity range 1 to 5 mm/μsec using ⅛-inch diameter spherical pellets is described. Pellet materials include aluminum, magnesium, steel, brass, lead, and zinc. Experiments relating to the mechanisms of cratering and the perforation of thin targets are presented. For the ⅛-in.

Impact ionization phenomena in AlGaAs/GaAs HEMTs
IEEE Transactions on Electron Devices, 1991The 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.

Hydroelastic Challenges for Wave-Impact Phenomena in Sloshing Flow
Volume 9: Odd M. Faltinsen Honoring Symposium on Marine Hydrodynamics, 2013Depending 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

Electrical contact phenomena during impact
IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1991The 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
1962Abstract : 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.
