In this chapter, we construct numerical solutions to the problems in the field of solid mechanics by combining the Boundary Element Method (BEM) with interpolation by means of radial basis functions. The main task is to find an approximation to a par

A boundary integral formulation of the linear elasticity problem for a multi-component composite is given. The fast BEM solver based on the adaptive cross approximation is then obtained by the data-sparse representation of the resulting Galerkin matr

SUMMARY The purpose of this paper is to present an adaptive finite element–boundary element method (FEM–BEM) coupling method that is valid for both two- and three-dimensional elasto-plastic analyses. The method takes care of the evolution of the

The efficient handling of matrices arising in surface interpolation and approximation with radial basis functions (RBF) is considered. To find a data-sparse approximation of the system matrix, the adaptive cross-approximation (ACA) technique is used.

We construct a convolution-thresholding approximation scheme for the geometric surface evolution in the case when the velocity of the surface at each point is a given function of the mean curvature. Conditions for the monotonicity of the scheme are f
