A History of Research and a Review of Recent Developments

Below-ground explosions 35
(K�5000 psi) at the Camp Gruber location in Oklahoma, USA, is given by
the heavy line in Figure 2.10. The figure also gives relationships for loam and
unsaturated clay. Other functions for TNT can be constructed using the values
for K listed in Table 2.1.
