摘要

The dynamic tensile fracture behavior of polymer bonded explosive simulant was investigated. The experimental test was performed on notched semi-circular bending (NSCB) samples of the material by using the split Hopkinson pressure bar(SHPB) apparatus. With the aide of a high-speed camera, the dynamic displacement and strain field during the dynamic fracture process were obtained by the digital image correlation (DIC) technique. Based on cohesive crack model (CCM), the numerical simulation of the same conditions was performed. Compared with the results obtained by simulation and experiment, the good agreement was found for the time history of tensile stress and the displacement and strain fields during dynamic fracture. The behavior of crack propagation of PBX during NSCB test was analyzed by the CCM. Furthermore, the width of crack in NSCB sample is about 15% smaller than the experimental results.
