Abstract
In this work, three percentages of constant loading are used for fatigue failure assessment. Fatigue behaviour under these three percentages of constant loadings is analyzed by using a new statistical-based approach known as integrated kurtosis-based algorithm for Z-notch filter (I-kaz). Fatigue tests were performed according to ASTM E466-96 standard with a strain gauge attached to the specimen being tested. A fatigue test was conducted under three loadings between 600–700 MPa and at a frequency of 8 Hz. A set of data acquisition systems was used to collect the fatigue strain signals. The I-kaz technique, which provides an I-kaz coefficient and a three-dimensional (3D) graphic, was used to describe and to evaluate the fatigue failure activities. The trends of I-kaz coefficients and of 3D graphics were compared to explain the fatigue damage induced by the three loadings.
Abstract
Für die diesem Beitrag zugrundeliegende Studie wurden drei Prozentsätze konstanter Beanspruchung zur Abschätzung von Ermüdungsschäden verwendet. Das Ermüdungsverhalten unter diesen drei Prozentsätzen wurde abgeschätzt, in dem ein neuer Statistik-basierter Ansatz gewählt wurde, der sogenannte Integrierte Kurtosis-basierte Algorithmus für einen Z-Kerb-Filter (I-kaz: integrated kurtosis-based algorithm for Z-notch filter). Die Ermüdungsversuche wurden entsprechend des Standards ASTM E466-96 mit einem Dehnungsmessstreifen auf der Probe durchgeführt. Der Ermüdungsversuch wurde mit drei Beanspruchungen zwischen 600–700 MPa bei einer Frequenz von 8 Hz durchgeführt. Die Dehnungssignale der Versuche wurden mit einem Datenerfassungssystem aufgezeichnet. Die I-kaz-Technologie, die einen I-kaz-Koefizienten und eine dreidimensionale Grafik liefert, wurde verwendet, um die Ermüdungsschäden zu beschreiben und zu evaluieren. Die Trends der I-kaz-Koeffizienten und der 3D-Grafiken wurden verglichen, um die Ermüdungsschädigung bei den drei Beanspruchungen zu erklären.
