Abstract

The purpose of this study is to set forth the mathematical framework for an efficient treatment of a plane dislocation loop in a two-phase material, and to carry the elastostatic part of the analysis far enough, so that the results are immediately tractable for applications to solid state. The two-phase material is idealized as two isotropic elastic half-spaces with perfect adhesion, while the loop is placed in a plane parallel to the interface. It is shown that the elastic fields can be obtained by differentiating two types of integrals and, thus, are readily evaluated for any shape of the loop for which the integrals are available from potential theory. Explicit results are given for circular prismatic and glide loops.

Zusammenfassung

Mit der vorliegenden Arbeit wird die Absicht verfolgt, den mathematischen Rahmen zu einer leistungsfähigen Behandlung von ebenen Versetzungsschleifen in einem Zweiphasenmaterial zu erweitern und den elastostatischen Teil der Berechnung so weit fortzuführen, daß die Resultate für die Anwendung in der Festkörperphysik unmittelbar zur Verfügung stehen. Das Zweiphasen-Material wird idealisiert durch zwei isotrope elastische Halbräume mit perfekter Adhäsion, während die Versetzungsschleife in einer Ebene parallel zur Trennfläche angenommen wird. Es wird gezeigt, daß die elastischen Felder durch Differentiation zweier Integraltypen und damit für jede beliebige Form der Versetzungsschleife erhalten werden können, für die die Integrale sich aus der Potentialtheorie ergeben. Explizite Resultate werden für kreisförmige prismatische und gleitende Schleifen angegeben.
