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

A stabilized nodal integration technique is adopted by adding the square of the residual of the equilibrium equation to the potential energy functional. An approach is proposed based on Voronoi diagram to evaluate nodal volumes accurately. It is a key issue for nodal integration of Galerkin meshless
