Abstract

Abstract

In this study, using a split Hopkinson pressure bar (SHPB), we assembled a fast-responding infrared temperature measurement system, capable of simultaneously obtaining the superficial temperature change of the HTPB propellant in impact experiments, to investigate the energy dissipation pattern of HTPB propellant under impact loading. The results show that the HTPB propellant exhibited visco-hyper elastic properties, and experienced significant temperature rise in high speed deformation. Based on the visco-hyper elastic constitutive model, we also introduced a heat softening function to more accurately describe the thermodynamic response of the HTPB propellant at high strain rates. Our results provide support for the analysis of thermo mechanical coupling of the solid composite propellant under impact loading.
