【Abstract】 A one dimensional viscoelasticity damage model about creep of plastic bonded explosives (PBX) is suggested in this paper. The numerical solution of the model shows good agreement with the experimental results of H.D. Johnson. It follows that thermal softening, settled upon by selection of binders and initial damage, settled upon by the granule characterization of explosives, are important factors influencing the creep damage properties of PBX materials. Analyses for the creep compliance show that the creep damage of PBX materials could be put under control, if reasonable viscosity coefficients are chosen.更多还原
