Abstract: The cumulative breakage probability by repeated stressing of γ-Al2O3 granules, was described using two models. The first model, where breakage probability by single stressing of granules remains constant, was not suitable for repeated stressing. The model was inappropriate to determine the change in the particle’s microstructure during stressing. Whereas in the second model, the hardening effect to be taken into account during stressing and was defined by a reduction factor of breakage probability. The deformation behavior of granules was used to indicate the change of microstructure of particles during stressing. In this case, the stiffness of the granules increased by means of plastic yielding and consolidation granules. In the compression test, the stiffness increased rapidly through fixed treatment. Meanwhile, in the case of rotated treatment the stiffness was significantly unaffected, as it was randomly distributed throughout the particle surface. Consequently, the cumulative breakage probability of rotated granules was lower compared to the fixed one.
