Damage characteristics and failure mechanism analysis of NEPE propellant at high strain rates

Damage characteristics and failure mechanism analysis of NEPE propellant at high strain rates

Abstract The study of mechanical properties and failure mechanism of propellants under impact loads is crucial for analyzing structural integrity of propellant charges. An experimental investigation was conducted on NEPE propellant using a separated Hopkinson pressure bar to conduct high strain rate...
