Das Bild zeigt einen typischen Prüfaufbau sowie eine Probe zur Durchführung eines CTOD-Tests zur Bewertung der Risswiderstandsfähigkeit von Stahl. Der Crack Tip Opening Displacement Test ist ein bruchmechanisches Prüfverfahren, bei dem die Öffnung der Rissspitze unter definierter Belastung gemessen wird. Er liefert wichtige Aussagen zur Zähigkeit und zum Widerstand eines Werkstoffs gegen Risswachstum, insbesondere bei tiefen Temperaturen oder hohen Beanspruchungen. Der CTOD-Test wird vor allem bei Offshore-Stählen, hochfesten Schiffbaustählen sowie sicherheitsrelevanten Konstruktionen eingesetzt und ergänzt klassische mechanische Prüfverfahren um eine realitätsnahe Bewertung des Bruchverhaltens.

CTOD test: Crack resistance of steel in the endurance test

The CTOD test is an important test standard for steel. It simulates the formation of cracks and helps to determine the material’s crack resistance. Read here how the test works and what advantages it offers.
