Abstract

Equation of state (EOS) efforts at National Nuclear Security Administration (NNSA) national laboratories tend to focus heavily on metals, and rightly so given their obvious primacy in nuclear weapons. Our focus here, however, is on the EOS of 'soft' matter such as polymers and their derived foams, which present a number of challenges distinct from those of other material classes. This brief description will cover only one aspect of polymer EOS modeling: treatment of shock-driven decomposition. Here, these interesting (and sometimes neglected) materials exhibit a number of other challenging features— glass transitions, complex thermal behavior, response that is both viscous and elastic—each warranting additional discussions of their own.

Foam Micromechanics

Journal Article Kraynik, A M ; Neilsen, M K ; Reinelt, D A ; ... - NATO Advanced Studies, Institute on

Foam evokes many different images: waves breaking at the seashore, the head on a pint of Guinness, an elegant dessert, shaving, the comfortable cushion on which you may be seated... From the mundane to the high tech, foams, emulsions, and cellular solids encompass a broad range of materials and applications. Soap suds, mayonnaise, and foamed polymers provide practical motivation and only hint at the variety of materials at issue. Typical of mukiphase materiaIs, the rheoIogy or mechanical behavior of foams is more complicated than that of the constituent phases alone, which may be gas, liquid, or solid.

Workshop introduction

Conference Streeper, Charles

The Department of Energy's National Nuclear Security Administration's Global Threat Reduction Initiative (GTRI) has three subprograms that directly reduce the nuclear/radiological threat; Convert (Highly Enriched Uranium), Protect (Facilities), and Remove (Materials). The primary mission of the Off-Site Source Recovery Project (OSRP) falls under the 'Remove' subset. The purpose of this workshop is to provide a venue for joint-technical collaboration between the OSRP and the Nuclear Radiation Safety Service (NRSS). Eisenhower's Atoms for Peace initiative and the Soviet equivalent both promoted the spread of the paradoxical (peaceful and harmful) properties of the atom. The focus of nonproliferation efforts has been rightlymore »« less

The equation of state and shock-driven decomposition of polymethylmethacrylate (PMMA)

Journal Article Coe, Joshua Damon ; Lentz, Meghan ; Velizhanin, Kirill A. ; ... - Journal of Applied Physics

We present new equations of state (EOS) for polymethylmethacrylate and its shock-driven decomposition products, generated in both tabular form and as linear U_S – u_p fits to all previously available shock data. Different approaches are taken for materials shocked above and below the apparent threshold for chemical reactions at pressures P ≈ 30 GPa. Both EOSs are calibrated to and compared with a broad array of experimental results, as well as new ab initio molecular dynamics simulations presented here. Comparisons are good in most cases, and we focus our particular attention on those observables that test the distinction between reactantsmore » and products.« less

In Defense of the National Labs and Big-Budget Science

Technical Report Goodwin, J R

The purpose of this paper is to present the unofficial and unsanctioned opinions of a Visiting Scientist at Lawrence Livermore National Laboratory on the values of LLNL and the other National Labs. The basic founding value and goal of the National Labs is big-budget scientific research, along with smaller-budget scientific research that cannot easily be done elsewhere. The most important example in the latter category is classified defense-related research. The historical guiding light here is the Manhattan Project. This endeavor was unique in human history, and might remain so. The scientific expertise and wealth of an entire nation was tappedmore »« less

Equation of State and Damage in Polyethylene

Technical Report Coe, Joshua Damon ; Brown, Eric ; Cady, Carl Mcelhinney ; ...

The dynamic response of polymers differs significantly from those of metals, upon which many of the National Laboratories' deformation, damage, and failure models are based. Their moduli, yield strength, and damage characteristics are highly strain rate-, temperature-, and phase-dependent, requiring models that encompass a wide range of phenomena including some not in equilibrium. Recently, Los Alamos developed the Glassy Amorphous Polymer (GAP)¹ model [1] to address limitations in existing models of polymer deformation. GAP captures both volumetric (equation of state) and deviatoric (shear) response, including a non-equilibrium component to the former (a feature determined to be crucial in capturing themore »« less
