The mechanical tests were performed on disks under diametral compression. In an extensive parametric study, the distribution of microcracks was varied for different particle sizes. The evolution of yield stress with diameter and the probability of failure in terms of Weibull distributions are investigated in detail. Finally, by means of a floodfill algorithm, we analyze the variation of the mean fragment size as a function of the density of defects. %G English %2 https://hal.science/hal-01595386/document %2 https://hal.science/hal-01595386/file/Blanc-PG-2017-CC_%7B8A5A3CB8-4AF4-44C6-A2A0-7C5965E04B2D%7D.pdf %L hal-01595386 %U https://hal.science/hal-01595386 %~ CIRAD %~ CNRS %~ UNIV-MONTP2 %~ INRA %~ IATE %~ LMGC %~ CGP-GATEWAY %~ AGREENIUM %~ MIPS %~ BA %~ UNIV-MONTPELLIER %~ INSTITUT-AGRO-MONTPELLIER %~ INRAE %~ INRAEOCCITANIEMONTPELLIER %~ UM-2015-2021 %~ INSTITUT-AGRO
