Discrete element simulation of the breakage behavior of porous granules utilizing bond models

Abstract In the development of ships, aspect collision safety plays a major role. this paper, approach to improve crashworthiness ships is fill already existing double hull with granular material. For purpose, material used be investigated numerically. A discrete element applied for in paper presented. Since breakage behavior particles particular interest, method together bonded particle method. This extended by model which able take into account micro-cracks occurring and energy dissipation caused them. Using other models method, simulations are carried out compared corresponding experiments. focus on uniaxial compression tests single systems. The single-particle determine various simulation parameters relevant individual terms geometry addition, multi-particle provide insight several particles, their interaction dynamics. These can test extent it possible represent porous fracture numerical means.
