Overview of crash and impact analysis at Lawrence Livermore National Laboratory

Description: This work provides a brief overview of past and ongoing efforts at Lawrence Livermore National Laboratory (LLNL) in the area of finite-element modeling of crash and impact problems. The process has been one of evolution in several respects. One aspect of the evolution has been the continual upgrading and refinement of the DYNA, NIKE, and TOPAZ family of finite-element codes. The major missions of these codes involve problems where the dominant factors are high-rate dynamics, quasi-statics, and … more

Imaging of surface structure with energy-dependent photoelectron diffraction

Description: Energy-dependent photoelectron diffraction (EDPD) has been used to determine the surface structure of a surface alloy. Direct imaging has been achieved by Fourier transformation of experimental energy-dependent photoelectron diffraction data. This holographic method, based upon the intersection of contour arcs associated with each measurement direction, can provide vectorial atomic positions with atomic resolution. Experimental analysis is supported by Fourier transformation of simulations from… more

Generalized perturbation method expansions of the total energy of an alloy

Description: The generalized perturbation method, commonly used in connection with the band energy contribution to the energy of a solid to approximate the total energy of an ordered configuration of an alloy, is reformulated with respect to total energy. The connection of the results derived here to those obtained based on the band energy is pointed out, and possible applications of the method is discussed.

Anaerobic biprocessing of low rank coals. Final technical report, September 12, 1990--August 10, 1993

Description: Coal solubilization under aerobic conditions results in oxygenated coal product which, in turn, makes the coal poorer fuel than the starting material. A novel approach has been made in this project is to remove oxygen from coal by reductive decarboxylation. In Wyodak subbituminous coal the major oxygen functionality is carboxylic groups which exist predominantly as carboxylate anions strongly chelating metal cations like Ca{sup 2+} and forming strong macromolecular crosslinks which contribute i… more

The Trade and Development Agency

Description: Congressional interest linking foreign aid more directly with commercial interests has grown in recent years as the U.S. budget becomes increasingly strained, constituent support for foreign aid dwindles, and U.S. industries seek Federal assistance. The Trade and Development Agency is one of several Government agencies involved in "aid for trade"--programs that combine development assistance and export promotion.
