Recently　developed　peridynamic　(PD)　simulations,　allowing　spontaneous　crack　nucleation　and　propagation,　have　been　conducted　to　investigate　the　dynamic　breakage　behavior　of　impact　spherical　particles　as　a　function　of　impact　speeds.　With　the　increase　of　impact　speed,　the　Hertzian　cracks,　primary　meridian　cracks,　secondary　meridian　cracks,　circumferential　cracks,　and　crack　bifurcations　are　observed.　The　crack　propagation　speeds　can　reach　62%　Rayleigh　wave　speed　at　impact　speed　of　20　m/s.　Then　with　the　further　increase　of　impact　speed,　crack　bifurcation　is　observed　due　to　dynamic　path　instability,　leading　to　the　catastrophic　failure　of　impact　spheres.　The　evolution　of　damage　ratio,　defined　as　the　ratio　of　broken　bonds　to　total　initial　bonds　in　PD　model,　agrees　with　previous　results　using　discrete　element　method　(DEM),　validating　the　current　model.　Furthermore,　the　comparison　between　computed　and　theoretic　contact　force　is　performed　along　with　experimental　measurements.　The　research　provides　additional　insights　into　breakage　mechanisms　of　particles.　©　2019　Elsevier　B.V.
