Abstract

Die Erfindung betrifft ein Verfahren zur Bestimmung der Restlebensdauer und/oder des Ermüdungszustandes von Bauteilen. Aufgabe der Erfindung ist es eine Möglichkeit vorzuschlagen, mit der der Ermüdungszustand und/oder die Restlebensdauer von Bauteilen aus plastisch verformbaren metallischen Werkstoffen zerstörungsfrei bestimmen zu können, ohne dass die vorab auf das jeweilige Bauteil bereits gewirkten Belastungen oder Vorschädigungen bekannt sind. Zur Bestimmung der Restlebensdauer und/oder des Ermüdungszustandes von Bauteilen aus plastisch verformbarem metallischem oder sprödem Werkstoff wird so vorgegangen, dass lokal definiert am Bauteil Spannungsamplituden innerhalb charakteristischer Zeitintervalle Δti mit diesen zugeordneten Lastspielzahlen pro Zeitintervall α(Δti) = ΔN (Δti) /Δti zeitbezogen bestimmt werden. Dabei aus der Wöhlerlinie des jeweiligen Werkstoffs die für die bestimmten Spannungsamplituden repräsentativen Lastspielzahlen NB (Δti) bis zum Erreichen der Bruchgrenze ermittelt und aus den gemessenen elektrischen oder magnetischen Rauschssignalen für größere Zeitintervalle ΔTm = ∑ Δti die fraktale Dimension DF (m) bestimmt und daraus die Restlebensdauer oder der Ermüdungszustand ermittelt wird.
