Nonlinear Equations Solver for Large Equations Sets Arising When Using BEM in Inhomogenous Regions of Nonlinear Material

Abstract

Realistic engineering problems often demand nonlinear material behaviour to be taken into account. BEM can be readily applied to nonlinear,potential problems in homogenous bodies. The standard_{1 2} technique is the Kirchhoff’s transformation However, this approach cannot be directly employed in the case of bodies composed of some subregions each of different material properties. The paper deals with the extension of Kirchhoff’s transformation idea to inhomogenous bodies in the context of boundary element method.
