We have conducted detailed 1- and 2-dimensional hydrodynamics calculations to assess the quality of simulations commonly made to understand various shock processes in a sample and to design shock experiments. We began with relatively simple shock exp

Los Alamos National Lab (LANL) is actively engaged in the development of a model to predict the formation of micron‐scale fragments ejected (ejecta) from shocked metals that have surface defects. The LANL ejecta model considers that the amount of e

Proton radiography (pRad) is a powerful new diagnostic with the potential of producing accurate (1%) direct density measurements from dynamically loaded materials. Experiments have been performed to investigate the feasibility of using proton radiogr

Dynamic damage evolution in materials is of growing interest, in particular, the role of defect structure on material strength during a dynamic experiment. Many studies in the past have seen strong correlations between the shockwave profile and the d

Lead is a material of fundamental scientific interest because of its relatively low melting point and ductility. Alloys of lead are used for practical reasons which include the desire to have a slightly harder form of the metal to be able to handle w

The importance of a microstructurally‐controlled Bauschinger component to defect storage during the shock loading process has been shown to be correlated to both quasi‐elastic release effects and reduced shock hardening in materials. In the curre

When highly polished metal surfaces melt upon release after shock loading, they exhibit features that suggest significant surface changes accompany the phase transition. The reflection of light from such surfaces changes from specular (pre-shock) to

Thermophysical properties of most liquid metals are difficult to measure because of the very high temperatures and pressures required, but they are important for several reasons. These include understanding the fundamental physics of liquid metals an

Several spallation experiments have been performed on uranium using gas gun driven normal plate impacts with VISAR instrumentation and soft recovery. The shock pressures achieved were 81, 53, and 37 kbar. This paper will focus on modeling the free su
