    Abstract
  • Based on the Monte-Carlo method, the meso-structural model of plastic bonded explosives (PBX) was established considering the grain size and location in random distribution by the non-linear finite element method. The influence of the binder and the defect hole to ignition characteristics of PBX in meso-structural was analyzed under shock and ramp loading. The results show that the critical pressure to ignite explosive rises with the increase of the binder content under shock and ramp loading. Compared with the results under shock loading, the critical pressure to ignite explosive under ramp loading is improved with the increase of the binder content. Also, the critical pressure to ignite explosive falls under shock loading, and rises under ramp loading due to the defect holes.
