This study focuses on the numerical modeling of the fragmentation under impact of individual 2D particles.We rely on a bond-based peridynamics approach for the modeling of constitutive behaviour andfailure of the particles. The so-called floodfill algorithm, classically used in image analysis, is employedto determine the size distribution of fragments as a function of geometrical parameters and density ofdefaults together with impact energy.Cette étude porte sur la modélisation numérique de la fragmentation de particules individuelles 2Dsous impact. L’approche utilisée pour la simulation du comportement mécanique à la rupture est lapéridynamique bond-based. La statistique des tailles de fragments est obtenue à l’aide d’un algorithmed’analys...
