In this work, despite the existence of several techniques aimed at the numerical solution of singular integrals, we aim to test the Gauss quadrature efficiency in the solution of the improper line integral that arises in the integration procedures typical of the Contour Element Method, when The fundamental solution is integrated along an element that contains its own point of origin, called the source point. In these tests it is possible to observe how much the presence of singularities, even weak ones, impose disturbance to the results, especially in the case of non-rectilinear elements, such as those that are approached here.
