Investigation on the impact and compression behavior of wet \upgamma -\hbox {Al}_{2}\mathrm{O}_{3} granules

The material behavior of dominant elastic–plastic \(\upgamma \)-\(\hbox {Al}_{2}\mathrm{O}_{3}\) granules has been experimentally studied by means of quasi static compression tests and dynamic impact tests until fracture. The obtained distributions of breakage velocity and specific breakage energy are compared. Thus, velocity dependent influences at stressing like viscous behavior can be derived. Additionally, the influences of particle size and moisture content on the material behavior are investigated.
