The mechanical properties of two types of explosives, press fit and melt cast, were studied at different temperature environments (-30 ℃, 20 ℃, and 50 ℃) using quasi-static and dynamic mechanical testing devices. The stress-strain curves and mechanical performance characteristics of the two explosives at different temperature environments were obtained. Under the same temperature conditions, the yield strength and elastic modulus of press fit and melt cast explosives increase with the increase of loading strain rate, exhibiting a strain rate enhancement effect. Under different temperature conditions, as the temperature increases, the yield strength and elastic modulus of press fit and melt cast explosives both rapidly decrease. The results show that this study can provide theoretical reference for the design of mechanical properties of charges.
