Abstract: This paper presents the results of mechanical tests of explosive samples. Strain diagrams and the dependence of Poisson's ratio on strain at a temperature of 20, 60, 80, 100$^\circ$C were obtained. Curves of the mechanical characteristics of the explosive versus temperature were plotted. The rigidity, strength, and deformability of the explosive were shown to decrease with increasing temperature.

Keywords: explosive, mechanical properties, strain diagram, Poisson's ratio, temperature.
