摘要

The dynamic compaction and spall response of a hydroxy-terminated polybutadiene bonded propellant(GSJ) and a composited-modified double-based propellant(CMDB) was studied. A series of planar impact experiments had been conducted. A simplified dynamic brittle fracture model is presented for solid propellent. Comparison of numerical and experimental results shows that this new model describes the spallation of solid propellant successfully.
