Weight functions and fundamental fields for the penny-shaped and the half-plane crack in the three-space. (English) Zbl 0601.73102

Weight functions permit to represent stress intensity factors as weighted averages of the externally impressed boundary tractions and body forces. In this paper the relevant weight functions of all three modes are represented in closed form with the aid of elementary transcendentals. Their derivation as displacements of fundamental fields is simple and without recourse to integral transforms of any kind.
