Boundary Integral Equations for the Three-Dimensional Helmholtz Equation
SIAM Review, 1974The relation between various boundary integral equation formulations of Dirichlet and Neumann problems for the three-dimensional Helmholtz equation is clarified. The integral equations derived using single or double layer distributions as well as those based on the Helmholtz representation using an unmodified free space Green’s function are presented ...

This chapter is concerned with the introduction of the basic integral equations for two-dimensional elastic linear material problems. It starts by briefly reviewing the partial differential equations for linear elastic material and introducing the necessary notations involved in the formulation.

Numerical Integration of the Boundary-Layer Equations
2000Numerical solutions of the boundary–layer equations are based on the assumption that the differential expressions in the partial differential equations can be approximated by difference expressions. This approximation, called discretisation can be obtained from a series expansion for the velocity components in the coordinate directions.

A Boundary Integral Equation Approach to Oxidation Modeling
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1985Thermal oxidation of silicon involves the diffusion of oxidant molecules from the gas-oxide interface to the oxide-silicon interface, and the transport of newly formed oxide away from the latter. Under suitable formulations these two processes can be shown to be boundary-value problems of harmonic and biharmonic nature.

Boundary Integral Equations and Boundary Elements Methods in Elastodynamics
2007We review the application of boundary integral equation (BIE) methods to elastic wave propagation problems. BIE methods express the wavefield as an integral equation defined over the boundary of the domain studied. They can be grouped into two families.

According to the Dirichlet existence-uniqueness theorem, there exists a unique harmonic function φ in Bi which assumes prescribed continuous boundary values on a Liapunov surface ∂B. To construct φ in Bi, we write $$\phi (\underline {\text{p}} ) = \mathop \smallint \limits_{\partial {\text{B}}} g(\underline {\text{p}} {\text{,}}\underline {\text{q}}

Boundary Integral Solutions of Laplace's Equation
Bell System Technical Journal, 1978Although Laplace's equation is simple, the region over which it is to be solved is often complicated. Both the shape of the region and the boundary conditions can induce solutions Φ which are singular at isolated points on the boundary of the region. Boundary integral equation methods are well-suited to the problem, reducing a two-dimensional partial ...

Based on [1], we have further applied the variational principle of the variable boundary to investigate the discretization analysis of the solid system and derived the generalized Galerkin's equations of the finite element, the boundary variational equations and the boundary integral equations. These equations indicate that the unknown functions of the
