dc.description.abstract | In a series of previous papers it was shown that the fracture of brittle materials such as rock subjected to a globally compressive stress field is accompanied by the formation of microdamage regions. Quantitative descriptions of these regions exist for isotropic materials. In the present paper the theory is extended to brittle materials which exhibit anisotropic fracture behavior due to the presence of a preferred prefracture flaw distribution. Results are computed for three orientations of a given flaw distribution and compared with some existing theoretical and experimental isotropic results. A new type of chip formation, not found in the isotropic case, involving multiple initiation sites, is predicted. In einer Serie von Arbeiten wurde gezeigt, daß der Bruch von sprödem Material zu dem auch Stein gehört, unter Einfluß eines global kompressiven Spannungsfeldes eine Beschädigung im Mikrobereich aufweist. Es gibt bisher quantitative Beschreibungen dieser Erscheinung für isotrope Materialien. In der vorliegenden Arbeit wird die Theorie auf spröde Materialien, die anisotropes Bruchverhalten zufolge vorhandener Risse zeigen, erweitert. Berechnungen werden für drei Richtungen von vorhandenen Rissen durchgeführt und mit einigen vorhandenen theoretischen und experimentellen verglichen. Mittels vieler Ansätze wurde eine neue Bruchform, die im isotropen Fall nicht vorkommt, vorausgesagt. Dans une série d'articles antérieurs on a montré que la fracture des matériaux fragiles — tels que la roche sujette à un champ d'effort globalement compressif — est accompagnée de la formation des régions de microendommagement. Des descriptions quantitatives de ce région, existent pour les matériaux isotropes. Ici la théorie est étendue aux matériaux fragiles qui exhibent un comportement anisotrope de la fracture par suite d'une distribution préferée des imperfections avant la fracture. Les résultats sont calculés pour trois orientations d'une distribution donnée des imperfections, et sont comparés avec des résultats actuels théoriques et expérimentaux pour le cas isotrope. On prédit une nouvelle type de la formation des copeaux — pas trouvée dans le cas isotrope — que mise en jeu les sites multiples d'initiation. | en_US |
