“…We will return to a comparison of DSC and macroscopic thermal explosion experiments in a later section. Probably the most successful approach at predicting large-scale thermal explosions is due to Tarver and coworkers, who developed simple sequential and autocatalytic kinetic models for a variety of explosives over the past 25 years (13)(14)(15)(16)(17). The approach assumes temperature-dependent thermal properties of both the solid and gas phases, uses activation energies similar to those in more complicated mechanisms, and optimizes the kinetic parameters against ODTX experiments.…”

The problem of laser initiation of high explosives in munitions is considered. In this situation, the laser illuminates a small spot on the casing, and lateral thermal transport affects the initiation temperature. We use a variational method to calculate the critical temperature for explosive initiation as a function the laser spot size, for common high explosives. The effect of the dwelling time of the irradiation is then evaluated. We demonstrate that in typical situations the critical temperature is determined by the dwelling time rather than by the laser spot size.

“…The main objectives of this study are to compare these results of specific heat capacity for a temperature range from 340 to 410 K with those obtained by other authors for RDX and similar PBX at room temperature (Rogers 1975;Tarver et al 1978;Dobratz 1981;Jones and Parker 2004;Xue et al 2010) as well as to evaluate the difference between the specific heat capacity value of a PBX based on RDX and the results obtained by calculation based on the mass fraction of individual compounds figures.…”

ABSTRACT:The experimental results of specific heat capacity of 2 plastic bonded explosives formulations based on 1,3,5-trinitroperhydro-1,3,5-triazine, using differential scanning calorimetry thermal analysis, and the theoretical ones calculated with the specific heat capacity and mass fraction of individual compounds are compared for a temperature range between 340 and 410 K. Apart the filler, the plastic bonded explosives composition includes the binder based on hydroxyl-terminated polybutadiene, the plasticizer bis (2-ethylhexyl) sebacate and the curing agent isophorone diisocyanate. The experimental and theoretical results showed a better approach when no curing agent is added. Without curing agent, the specific heat capacity of plastic bonded explosives increases linearly with temperature. When plastic bonded explosive is cured, the specific heat capacity is nearly constant until 380 K and decreases linearly for higher temperature values. These results suggest that phase change requires adjusting parameters to different heating rates in order to describe adequately the experimental data.
