Abstract
The collapse of a spherical pore in granular explosives due to shock loading is studied by the two-dimensional hydrocode DEFEL. The calculations include the effects of compressibility, elastic-plastic constitutive equations, viscosity, and conductivity. A spherical pore collapses into an ellipsoid shape giving rise to high temperature regions of hot spots. For micro-pores of diameters below a few hundred microns, the strain rate in localized regions is in the range of 10
6 to 10
9 per second. Without conductivity, the temperature increases with decreasing diameter. This trend is reversed in a very small diameter range due to the effect of conductivity.
