    Description / Table of Contents: Übersicht Für das Titelproblem wird hier erstmals eine vollständige Lösung mit expliziten Ausdrücken für die Spannungen und Verschiebungen im transversal-isotropen Raum mit zwei Einzellasten senkrecht zu einem Kreisriß angegeben. Die Herleitung beruht auf neueren Ergebnissen des Autors in der Potentialtheorie. Die Ergebnisse können als Greensche Funktionen für den allgemeinen Fall antisymmetrischer Relastung benutzt werden, so daß dessen vollständige Lösung durch Quadraturen darstellbar ist. Schließlich werden verschiedene Anwendungen in der Bruchmechanik betrachtet.
    Notes: Summary A complete solution is given for the first time to the title problem. Explicit expressions are derived for the field of stresses and displacements in a transversely isotropic space weakened by a penny-shaped crack and subjected to two antisymmetrically applied normal concentrated forces. The method is based on the new results in potential theory obtained by the author earlier. The presented results may be used as Green's functions for a general case of antisymmetric loading so that the complete solution can be presented in quadratures. Several specific applications to fracture mechanics are considered.
