Micro-Macro Breakage Behavior of Elastic-Plastic Granulates by Compression

This paper presents the breakage behavior of a zeolite granulate in compression tests. The compression behavior of this granulate is described by means of a force‐displacement curve, the application of Hertz‐Huber contact theory, and continuum mechanics. The effects of granulate size and stressing velocity on the breakage force and contact stiffness during elastic and elastic‐plastic deformation are examined. It is shown that the zeolite granulates with elastic‐plastic behavior have viscous properties as well. The breakage probability is approximated by the Weibull distribution function. The behavior of the granulates during compression under conditions of repeated loading‐unloading was investigated. The breakage behavior of a zeolite granulate in compression tests is presented. The compression behavior is described by means of a force‐displacement curve, the application of Hertz‐Huber contact theory, and continuum mechanics.
