Finite Elemente Verfahren in der Bruchmechanik

  • Chapter
Book cover Finite Elemente in der Bruchmechanik

Zusammenfassung

Im letzten Jahrzehnt ist die numerische Analyse bruchmechanischer Aufgabenstellungen zu einem Forschungszweig geworden, der durch ein hohes Maß an wissenschaftlicher Aktivität gekennzeichnet ist. Übersichtsartikel über die Anwendung numerischer Verfahren — insbesondere der Methode der Finiten Elemente — in der Bruchmechanik erscheinen mit gewisser Regelmäßigkeit in der Literatur /1/, /2/, /3/, /4/. In diesem Beitrag wird auf die Berechnung des singulären Spannungsfeldes um die Rißspitze und der damit assoziierten bruchmechanischen Kenngrößen und Parameter eingegangen. Inelastisches (z.B. elasto-plastisches) Bruchverhalten, welches in geeigneter Weise mit konventionellen, nichtsingulären Elementen beschrieben wird, wird an anderer Stelle eingehend behandelt. Die hier dargelegten Entwicklungen beziehen sich im wesentlichen auf die in der linear-elastischen Bruchmechanik charakteristischen Singularitäten für ebene und räumliche Probleme.
