AbstractwThree numerical adaptive integration schemes for almost singular functions occurring in the Boundary Element Method, which use subdivision of a domain or moving of nodes, are discussed. Some numerical examples show efficiency of the methods.

The authors present a new singular function boundary integral method for the numerical solution of problems with singularities which is based on approximation of the solution by the leading terms of the local asymptotic expansion. The essential boundary conditions are weakly enforced by means of app
The mixed boundary value problem in three-dimensional linear elasticity is solved via a system of boundary integral equations. The Galerkin approximation of the singular and hypersingular integral equations leads to (hyper)singular and regular double integrals. The numerical cubature of the singula
