Excerpt from book: 1943-1944 The work of 1943-1944 was directed pointedly at filling certain gaps in our information, with full knowledge that the defensive crisis was past and that we were putting together what would be needed to leave a reasonably clear record for our successors. One new field was investigated to a slight extent, that of penetration in soils. The previous work in concrete having proved inadequate on the side of study of concrete properties, a considerable effort was made on the concrete properties survey. Finally the large series of tests in Oklahoma was completed. These last consisted of studying the effects of detonating appropriately scaled charges in earth at varying distances from targets of five scales. The charge for the full-scale target was 1000 Ib. of TNT, while a few charges of 3200 Ib. of amatol were also detonated. At the conclusion of this year, a large number of interim reports were rendered, as described in more detail later. The above chronological survey will perhaps have illustrated with sufficient clarity what the principal contributions of the Committee can be said to have been. They may be summarized as follows: 1. Evaluation of prior literature of terminal ballistics. 2. Working up of pertinent data on the terminal ballistics of steel, principally taken from Service sources with some small additions from our own work or that of NDRC. 3. A very large addition to the data on and interpretation of the local effects of impact and explosion on reinforced concrete. This will perhaps be looked upon by most people as the major contribution of the Committee. 4. Preliminary studies in the much neglected field of the penetration of projectiles into earth. 5. Initiation of studies in this country on the characteristics of detonations in air and the ...
