What is Shielding of Crack Tips by Dislocations about?
The state ofthe continuum mechanical description of plasticity near cracktips is not satisfactory. However, the modification of stresses at crack tips by dislocations was calculated in recent papers. The result is that dislocations change the local stress intensity considerably and thus shield crack tips against the applied loads. The goal of this publication is to introduce into these problems by presenting the relevant results of anti-plane strain calculations which can be obtained readily with help of complex functions. ## Abschirmung von Rißspitzen durch Versetzungen Die kontinuumsmechanische Beschreibung von Plastizität in der Nähe von Rißspitzen ist bisher nicht zufriedenstellend. In neueren Arbeiten wurde daher direkt die Veränderung der Spannungen an Rißspitzen durch dort befindliche Versetzungen berechnet. Es stellte sich heraus, daß Versetzungen den lokalen
