Abstract

In order to obtain mechanical properties of propellant under different strain rate, with the universal testing machine and the split Hopkinson pressure bar (SHPB), the uniaxial compression tests of propellant have been performed at the strain rate from10-3 to 10³s-1. The results show that the propellant has significant strain rate effect. Zhu Wang Tang(ZWT) constitutive was adopted to describe the mechanical behavior of the propellant; the coefficients of the constitutive equation were obtained by the least square method and used in the numerical simulation. Compared with the numerical simulation, experiments show that numerical simulation may well describe mechanical properties of the propellant under high strain rate.

Key words： propellant; SHPB; high strain rate; Zhu Wang Tang constitutive; numerical simulation
