Title
Ermittlung der Fliekurven von Feinblechen im ebenen Torsionsversuch (IFU Berichte aus dem Institut fr Umformtechnik der Univer,Used
Delivery time: 8-12 business days (International)
Bei der umformenden Bearbeitung von Blechen ist neben den klassischen Festigkeits und Zhigkeitskennwerten naturgem das plastische Werkstoffverhalten von besonderem Interesse. Zur Kennzeichnung dieses Verhaltens wird im allgemeinen die Flie kurve kf( ) angegeben. Diese legt den Wert der Fliespannung k f fest, die unter einachsiger Beanspruchung zur Einleitung oder Aufrechterhaltung plastischen Flieens bei einem bestimmten Umformgrad (bzw. Vergleichsumformgrad v) notwendig ist. Die Kenntnis der Fliekurve gestattet in der praxis, Bleche fr bestimmte Verfahren auszuwhlen, bzw. unterschiedliche Chargen zu vergleichen; dies wird ergnzt durch die Anwendung als Rechengrundlage fr die Ermittlung von Umformarbeiten un krften zur Auslegung von Verfahren und Anlagen /1, 2/. Mit zunehmender Bedeutung numerischer Simulationsverfahren in der Umformtechnik, bei denen das Werkstoffverhalten im wesent lichen durch die Fliekurve reprsentiert wird, wchst der Bedarf an verllichen Werkstoffdaten. Die grundstzlich experimentelle Ermittlung der Fliekurven von Blechwerkstoffen bereitet keine Schwierigkeiten, solange eine ausreichende Dicke zur Entnahme von massiven (Zug oder Stauch) Proben vorhanden ist /3, 4, 5/. Feinbleche mit einer Dicke unter 3 mm hingegen sind nur mit erheblichen Einschrn kungen durch konventionelle Prfmethoden erfabar.
