DIRECT EVALUATION OF CAUCHY PRINCIPAL VALUE INTEGRALS IN BOUNDARY ELEMENTS FOR INFINITE AND SEMI-INFINITE THREE-DIMENSIONAL DOMAINS

O. J. B. Almeida Pereira and P. Parreira

ABSTRACT

Algorithms for the direct numerical evaluation of Cauchy Principal Value integrals in three-dimensional problems have been recently implemented. An application of one of these algorithms to infinite boundary elements and to semi-infinite special fundamental solutions is discussed.
