,The “Send More Money” Problem,erimental investigation, it was found that a low traverse speed rate has destructive effects on the material with significant weight and volume loss of the material. Surface topography was characterized by a formation of protrusions, depressions and craters. Subsurface material failure of up to 200 µm was detected.

https://doi.org/10.1007/0-387-27650-5l. In this paper the kinetic behavior and fragmentation of particles has been analyzed in a wide range of different conditions. New insights into fragmentation of the particles especially at higher pressures can explain the behavior of experimental cutting studies where higher pressures did not prov

Discrete and Interval Relations,e material. ConSus shows almost no significant effect on abrasive size distribution while commonly used injector systems shifts a tremendous portion of the original abrasive to smaller grain sizes. Therefore, the results enhance process understanding and revision of existing process models for futur

By comparing the achieved hydrodynamic effects of PWJ on titanium and aluminium, significant differences in the depth of erosion and its course can be observed due

https://doi.org/10.1007/978-3-319-54792-3 investigate the concrete erosion resistance. The influence of the concrete age on the resistance to fast-flowing liquids has been proven. After a year, the concrete resistance increased by about 36% in the case of the pure water jet, and 28% in the case of the abrasive water jet.
