PBX断裂力学行为研究进展
Researoh Progress on Fracture Mechanical Behaviors of PBX
摘要
Abstract
In terms of the commonly used experimental methods, mesoscopic fracture modes, macroscopic fracture mechanics and dynamical fracture, the research works on the fracture mechanical behaviors of PBX at home and abroad were reviewed.The macroscopic and mesoscopic-fracture features and characterization methods of PBX were introduced.The effects of mesostructure, mechanical feature, temperature and loading rate on the fracture behavior of PBX were discussed.It is pointed out that the research on PBX mesocrack initiation and extension, macroscopic fracture initiation mechanism and the crack extension behavior under dynamical loading of PBX should be carried out, and the composite fracture criterion fitted the characteristics of PBX should be established.With 51 references.关键词
