Testing low-cycle material properties with micro-specimens*
-
Dariusz Boroński
Abstract
New possibilities of low cycle fatigue material properties testing with the use of micro-specimens are presented in this publication. The discussed solution is of great significance for analysis of local properties of a material, e. g. in welded structures. Properties of a material determined in the manner presented in this publication find application both in fatigue life assessment (fatigue life curves) and in material modeling (cyclic stress-strain curves), e. g. in numerical analysis of local strain and stress that occur in structural components.
Kurzfassung
In diesem Beitrag werden neue Möglichkeiten für die Prüfung der LCF-Eigenschaften mit Mikroproben vorgestellt. Die diskutierte Lösung hat große Signifikanz für die Analyse der lokalen Eigenschaften eines Materials, insbesondere in geschweißten Strukturen. Die Eigenschaften, die auf die in diesem Artikel vorgestellten Weise bestimmt wurden, finden sowohl in der Lebensdauerabschätzung (Lebensdauerkurven) als auch in der Materialmodellierung (zyklische Spannungs-Dehnungs-Kurven) Anwendung, insbesondere in der numerischen Analyse von lokalen Dehnungen und Spannungen, die in Strukturbauteilen auftreten.
