Viscoelastic properties of polymer bonded explosive material PBX-9501 were studied by Material Point Method (MPM) for the first time. The homogenization problem was studied thoroughly. The material point resolution issue, system size effect and time step problem that related to the MPM simulation were also studied and determined. The simulation results were compared with the experimental data and the third-order upper- and lower bounds. The particle shape and distribution effect, as well as temperature effect to the viscoelastic properties of PBX-9501 were also studied.
