Abstract
The dynamic Brazilian tests and compression experiments were performed on a polymer bonded explosive (PBX) simulant by using split Hopkinson pressure bar (SHPB) and high-speed photography. Based on digital speckle correlation method, the displacement and strain fields on sample surface under different loadings were analyzed, and the dynamic deformation and fracture mechanisms of the specimen were discussed. The results obtained from the experiments are in agreement with the theoretical analysis. The feasibility that the digital speckle correlation method is used to study the dynamic behavior of explosive materials is verified.
