On the application of generic BE substructuring algorithm to analyze threedimensional composite materials
Abstract
A generic 3D boundaryelement substructuring algorithm, based on iterative solvers, is applied to solve problems involving composite materials. The substructuring technique is optimal regarding memory requirements for storing the resulting sparse matrices, and its efficiency is increased by implementing structured matrixvector products in the builtin Krylov solver. Moreover, special integration techniques are employed to effect the modeling of thinwalled parts of the composites, such as thin layers or reinforcing elements. To test the performance of the algorithm, effective mechanical properties of carbonnanotubereinforced composites are estimated by analyzing representative volume elements. The advantages of the coupling algorithm for developing parallel BE codes are also highlighted.

In domain decomposition algorithms with more than a few subdomains, there is a crucial need for a mechanism to provide for global communication of information at each step of the iterative process. The convergence rate will decay rapidly with an increasing number of subdomains if communication is only between neighboring subdomains. For iterative substructuring algorithms (those domain decomposition algorithms that use nonoverlapping subdomains), the method that provides for good global communication in two dimensions does not work well for problems in three dimensions. In this paper we present an alternative approach for providing global communication that works well in threemore »

Threedimensional nuclear magnetic resonance and xray microtomographic imaging of composite materials
This paper presents a newthreedimensional nuclear magnetic resonance (NMR) imaging technique for nondestructive evaluation of greenstate ceramic composite materials. The technique is based on a 3D backprojection protocol for data acquisition combined with a Radon reconstruction technique. Particularly for NMR of solid materials, this imaging protocol can provide higher three dimensional spatial resolution than is possible with commonly applied sliceselection protocols. The applicability of this 3D NMR imaging technique was demonstrated using whiskerreinforced Si{sub 3}N{sub 4}/Si{sub 3}N{sub 4} ceramic composites. While NMR is a sensitive and unique method for spatial discrimination of chemical properties (e.g., organic distributions), xray CT ismore » 
A parallel implementation of an iterative substructuring algorithm for problems in three dimensions
Numerical results from a parallel implementation of a class of iterative substructuring algorithms are reported. The algorithms are for solving selfadjoint elliptic partial differential equations in three dimensions. Results are given for several variants of the algorithm. In the first variant, exact interior solvers are used; in the second, one multigrid Vcycle is used to solve the interior problems approximately. The results are compared with theoretical behavior of the algorithm reported in previous work. A numerical experiment involving the equations of linear elasticity is also included. 
Algorithm for the calculation of threedimensional ICRF fields in tokamak geometry
One of the most promising schemes for heating plasmas to thermonuclear temperatures in magnetic fusion devices is radiofrequency heating, particularly at the ion cyclotron resonance frequency. Most studies of this problem assume the magnetic field that confines the plasma to be constant or at best onedimensional, whereas in reality it is quite complex. In this paper the authors introduce a computational scheme that permits tractable calculation of threedimensional fullwave solutions to the VlasovMaxwell equations under typical experimental conditions associated with the ion cyclotron range of frequencies. The method is unique in that power deposition to the plasma is determined viamore »
