Abstract

The plane problem of a central crack in a rectangular sheet of orthotropic material is considered. The solution is found by an extension of the modified mapping-collocation technique, originally formulated for plane isotropic analysis. Application of the technique outlined in this paper for plane orthotropic problems to a wider class of geometries and loading is evident. The numerical results indicate a dependence of the orthotropic stress intensity factors on both geometric and elastic constants over a certain parameter range.

Résumé

On considère le problème plan d'une fissure au centre d'une tôle mince rectangulaire d'un matériau orthotrope. La solution résulte d'une extension de la technique modifiée de représentation conforme par correspondance point par point, qui fut à l'origine suggérée pour l'analyse de conditions

L'application de la technique développée dans le mémoire pour des problèmes plans et orthotropes, à une classe plus large de géométries et de conditions de mise en charge, est évidente.

Les résultats numériques indiquent que les facteurs d'intensité de contrainte en conditions orthotropes dépendent à la fois des constantes géométriques et des constantes élastiques, du moins dans une certaine gamme de leurs valeurs.

Zusammenfassung

Es wird das plane Problem eines Risses im Zentrum eines Feinbleches aus orthotropen Material behandelt.

Die Lösung ergibt sich aus einer Ausweitung des abgewandelten Verfahrens der konformen Darstellung Punkt fur Punkt, welche urspriinglich für die Untersuchung der planen und isotropen Bedingungen vorgeschlagen worden war.

Die Anwendung des in diesem Bericht für plane and orthotrope Probleme dargelegten Verfahrens auf andere geometrische Formen and unterschiedliche Belastungsweisen ist selbstverständlich.

Die numerischen Ergebnisse zeigen eine Abhängigkeit der orthotropen Spannungsintensitätsfaktoren von den geometrischen and den elastischen Konstanten über einen gewissen Bereich der Parameterwerte.
