Zusammenfassung
Die Arbeit konzentriert sich auf die Schädigungsentwicklung an zyklisch hochbelasteten Kanten von Stanz- oder Schneidwerkzeugen. Zur Untersuchung der Schädigungsentwicklung wurde ein zyklischer Kantenstauchversuch entwickelt, mit dem Belastungen ähnlich jenen von Kanten von Stanzwerkzeugen simuliert werden können. Mit diesem Test wurden das lokale Verformungsverhalten und die Schädigungsentwicklung nach verschiedenen Lastzyklen analysiert. Die Tests wurden an einem nach dem Elektroschlacke-Umschmelzverfahren hergestellten Kaltarbeitsstahl des Typs K340 Isodur durchgeführt.
Summary
The paper deals with damage evolution near cyclically loaded edges of stamping or cutting tools. A specific cyclic edge-loading test procedure has been developed for characterising the behaviour of edges that are subjected to cyclic loading under high compressive mean stress. With this procedure, the local deformation behaviour and the damage evolution can be analysed after different load cycles. A cold work tool steel grade K340 Isodur produced by electroslag remelting technology was investigated.
