Abstract

A survey of existing solutions describing the stress distribution around the crack tip of an initially curved sheet is made and a method for estimating approximate stress intensity factors of other more complicated shell geometries is discussed.

Résumé

Il est procédé à une Etude des solutions existantes qui permettent de décrire la distribution des tensions au voisinage de l'extrémité d'une fissure dans une tôle mince présentant une courbure donnée.

L'on discute également une méthode d'estimation approchée des facteurs d'intensité de contrainte dans le cas d'enveloppes à géométrie plus complexe.

Zusammenfassung

Der Verfasser gibt cine Übersicht der Lösungen, welche die Spannungsverteilung in der Umgebung der Spitze eines Risses in einem vorgebogenen Blech beschreiben. Außerdem wird ein Verfahren besprochen, nach dem Spannungsintensitätsfaktoren im Falle komplizierterer geometrischer Formen näherungsweise geschätzt werden können.
