Abstract

This paper analyzes the functional relationship of pressure induced in the gap versus distance travelled. P = k e^−ax^. An analytical shock matching calculation is described to evaluate the constant k as a function of the density and the velocity of detonation of the donor explosive. TDL code is used to check the values of the constants for several donor explosives, and to compute the decay constant a. Functions for pentolite are compared with experimental data from bibliography. The method can be used to predict equivalent gap test thicknesses for donor explosives different from the commonly used pentolite.

## Abstract By means of shock‐wave measurements it was possible to calibrate the BICT‐gap test. The relation between the height of the gap and the shock‐wave peak pressure at the end of the gap is described. From other considerations the range where the test can be used, can be obtained. BICT‐gap t
