TL;DR: In this article, the radial integration method is presented for transforming domain integrals into equivalent boundary integrals. But the radial basis functions are not used in the proposed method, so no singularities exist at internal points.
Abstract: In this paper, a simple and robust method, called the radial integration method, is presented for transforming domain integrals into equivalent boundary integrals. Any two- or three-dimensional domain integral can be evaluated in a unified way without the need to discretize the domain into internal cells. Domain integrals consisting of known functions can be directly and accurately transformed to the boundary, while for domain integrals including unknown variables, the transformation is accomplished by approximating these variables using radial basis functions. In the proposed method, weak singularities involved in the domain integrals are also explicitly transformed to the boundary integrals, so no singularities exist at internal points. Some analytical and numerical examples are presented to verify the validity of this method.

TL;DR: In this article, the authors describe the application of boundary element methods (BEM) in solid mechanics, beginning with basic theory and then explaining the numerical implementation of BEM in nonlinear stress analysis.
Abstract: From the Publisher: This monograph describes the application of boundary element methods (BEM) in solid mechanics, beginning with basic theory and then explaining the numerical implementation of BEM in nonlinear stress analysis. In addition, the authors have developed state-of-the-art BEM source code, available for the first time on a CD-ROM included with the book.

TL;DR: In this article, a boundary element method without internal cells is presented for the analysis of elastoplastic problems, based on an effective transformation technique from domain integrals to boundary integrals.
Abstract: In this paper, a new and simple boundary element method without internal cells is presented for the analysis of elastoplastic problems, based on an effective transformation technique from domain integrals to boundary integrals. The strong singularities appearing in internal stress integral equations are removed by transforming the domain integrals to the boundary. Other weakly singular domain integrals are transformed to the boundary by approximating the initial stresses with radial basis functions combined with polynomials in global coordinates. Three numerical examples are presented to demonstrate the validity and effectiveness of the proposed method. ©2002 ASME

TL;DR: In this article, a new method is proposed for estimating temperature-dependent thermal properties using solutions to transient inverse heat conduction problems, where the unknown thermal property is treated as the optimization variable, and the errors to be minimized are the differences between the calculated temperatures and the measured ones.
