The main object of this paper is to reveal basic response of solid rocket fuels to different working conditions such as variable strain rates or temperature. Experimental data acquired during experimental tests is a base for development of a suitable constitutive model for homogeneous solid propellants. In the world literature there is still insuffcient information about typical mechanical features for considered materials. Universal standards for carrying out typical strength experiments have not yet been fully elaborated for this type of materials. Such problems as quasi-static strain range for solid propellants or so called scale effect are still not standardized. Though, this paper is a next step in preliminary investigation devoted to modeling of nonlinear properties of solid propellants. In particular, the infuence of temperature and strain rate on selected mechanical parameters variations is discussed.
