Practical Issues Associated with Mortar Projections in Large Deformation Contact/Impact Analysis

Description: Several recent works have considered variants of the mortar-finite element method for numerical treatment of contact phenomena. The method has shown considerable promise for the spatial discretization of contact interactions, particularly for kinematically linear applications where one or both of the contacting surfaces are flat. Desirable features already demonstrated for the method in this specialized setting include passage of patch tests, preservation of convergence rates that would be obta… more

A 3D Contact Smoothing Method

Description: Smoothing of contact surfaces can be used to eliminate the chatter typically seen with node on facet contact and give a better representation of the actual contact surface. The latter affect is well demonstrated for problems with interference fits. In this work we present two methods for the smoothing of contact surfaces for 3D finite element contact. In the first method, we employ Gregory patches to smooth the faceted surface in a node on facet implementation. In the second method, we employ a… more

Thermodynamic Modeling of the SRS Evaporators: Part I. The 2H and 2F System

Description: Accumulations of two solid phases occurred in the Savanah River Site (SRS) 2H-Evaporator system since late 1996. The aluminosilicate scale deposits caused the evaporator to become inoperable in October 1999. Accumulations of the diuranate phase have caused criticality concerns in the SRS 2H-Evaporator. In this study, thermodynamically derived activity diagrams, also known as stability diagrams, are developed from historic analytic data from the SRS 2H-Evaporator system feed tank (Tank 43H) and … more

Chemical separations schemes for partitioning and transmutation systems.

Description: In the initial phase of the U.S. Accelerator Transmutation of Waste (ATW) program, a single-tier system was foreseen in which the transuranics and long-lived fission products (specifically, {sup 99}Tc and {sup 129}I) recovered from spent LWR oxide fuel would be sent directly to an accelerator-driven transmuter reactor [1]. Because the quantity of fuel to be processed annually was so large (almost 1,500 tons per year), an aqueous solvent extraction process was chosen for LWR fuel processing. Wit… more
