Smoothly waning, symmetrically expanding, cavity-pressure loads in earth materials

Description: An approximate solution for the pressure loading required to expand a spherical cavity in rock and soil targets is derived. A dual characterization of fracture and flow material model is used. Frictional resistance to flow is also included. Non-linear volumetric strain hardening is modeled with bi-linear curves and unloading is assumed to be non-dilative. Applications of this solution form to the prediction of pressure loading on slender, convex-nosed earth penetrators and on spherically-nosed … more

Analytical and experimental evaluation of a proposed self-forging fragment munition

Description: Analytical and experimental tools have been used to study the formation of a proposed self-forging fragment projectile. The primary objective of this study is the determination of the interior and exterior shape of the fully formed fragment, and to determine if the fragment tumbles in flight. In addition, it is of interest to compare computer predictions to experimental results. An experiment was performed using high speed photography and high-energy flash x-ray radiography to study liner and c… more

Inclusive Particle Production at Forward Angles from Collisions ofli ght Relativistic Nuclei, Part III: Data Tables

Description: This document contains data tables on microfiche of single particle inclusive cross sections of protons, deuterons, tritons, {sup 3}He, {sup 4}He, {sup 6}He, {sup 8}He, and {pi}{sup -}. The production of these fragments was measured in collisions of 1.05 GeV/A and 2.1 GeV/A proton, deuteron, alpha and carbon projectiles as well as 0.4 GeV/A alpha particles on targets of C, Cu, Pb, and H (from a CH{sub 2}-C subtraction), using a double focusing spectrometer. Only fragment emission in the region … more
