Numerical Experiments Using CV-BEM

In this chapter we present numerical results that show the accuracy and capability of the CV-BEM. In numerical examples we reveal the importance of using a complete set of basis functions and accounting for the asymptotic behavior of functions at singular points, in particular, by employing tip elements. Under a reasonably chosen approximation, a solution for displacements and SIF normally has at least three correct significant digits even for a rather small number of boundary elements. It is sufficient to follow the simple general rules discussed below.
