Abstract In this paper we consider all difficult integrals required by collocation and Galerkin BEMs, when these are applied to weakly singular and singular 1D integral equations. In particular we show that they can be evaluated very efficiently by using very simple quadrature formulas. Several numerical examples are presented.
