Beschreibung:
The compression, deformation and material behavior of moist spherical elastic-plastic zeolite 4A granules under multiple stressing conditions at unique and random contacts were experimentally studied with the help of uniaxial diametrical compression tests. The force-displacement curves were approximated and the coefficient of restitution was determined using appropriate mechanical models from literature. The phenomenon of cyclic hardening was studied and the critical number of cycles required to reach fracture was determined. Furthermore, the influence of particle size and moisture content on the material behavior at cyclic loading, the coefficient of restitution, and the critical number of cycles required to reach fracture were investigated. In order to optimize processing, transportation, storage and handling of zeolite 4A granules, their material behavior at periodic and cyclic compressive loadings were investigated. The phenomenon of cyclic hardening was studied and the coefficient of restitution was determined. The influences of particle size, moisture content, and stressing intensity on the deformation behavior are discussed.
