Impact by laser shot, however, differs technically from that by material collisions.
Namely, the true-event waveform consists of separate peaked waves and must start with a positive peak due to the compression of the sensor material by collision.
The waveform of the hypervelocity impact read by the CVA consists of discrete wave packets and the first pulse clearly starts with a positive peak due to the compression of the sensor material by collision.
The observed increase in the smoothness of the film due to the inclusion of hydrogen in the background gas is believed to stem from an enhancement of the transferral of kinetic energy from the ablated material through collisions with both hydrogen and argon.
The considered chain model reveals some phenomena typical for waves of failure or crushing in constructions and materials under collision, waves in a structure specially designed as a dynamic energy absorber and waves of phase transitions in artificial and natural passive and active systems.
Predicting and controlling flexible materials and collisions, however, is tricky.
Cars could be made out of lighter materials for collision-free environment to make them much more energy efficient.
"L. A. Confidential" did justice to Mr. Ellroy's juicy material about the collision of power, celebrity and economic development in Los Angeles of the 1950's.
This value was almost constant, regardless of the splat material and the collision conditions.
Based on material tests, the collision behavior of γ-Al2O3 particles was characterized and incorporated into the contact model.
