The Time-temperature Superposition Principle And The Properties Of High Explosives(HE)

The properties of weapon-used high explosive under aging condition are analyzed in this thesis. Applications of the Time-Temperature Superposition (TTS) principle on the research of the properties of the typical viscoelastic materials (propellants) are summarized. By applying the Time-Temperature Superposition (TTS) principle, the regularities of the behavior of these typical high explosives (HE) brought by the effect of time and temperature are analyzed. By using Arrhenius equations, the parameters of the thermal decomposition of these typical explosives are statistically analyzed; therefore the time's relationships of the mechanical properties of explosives given the same decomposition state under different temperature are computed. Compared by the computational results from the Time-Temperature Superposition (TTS) principle, the high explosives can be studied whether singleness reaction or complex reaction by applying shift factor. It is quite effective for the properties of high explosive by applying the Time-Temperature Superposition (TTS) principle.
