Understanding the fatigue behaviour of structural components under
variable load amplitude is an essential prerequisite for safe and
reliable light-weight design. For designing and dimensioning, the
expected stress (load) is compared with the capacity to withstand
loads (fatigue strength). In this process, the safety necessary for
each particular application must be ensured. A prerequisite for
ensuring the required fatigue strength is a reliable load
assumption. The authors describe the transformation of the stress-
and load-time functions which have been measured under operational
conditions to spectra or matrices with the application of counting
methods. The aspects which must be considered for ensuring a
reliable load assumption for designing and dimensioning are
discussed in detail. Furthermore, the theoretical background for
estimating the fatigue life of structural components is explained,
and the procedures are discussed for numerous applications in
practice. One of the prime intentions of the authors is to provide
recommendations which can be implemented in practical applications.

Die Betriebsfestigkeitsprufung von Bauteilen ist u. a.
erforderlich, um ihre Lebensdauer zu berechnen. Dazu werden
verschiedene Methoden angewendet, die jeweils Vor- und Nachteile
aufweisen. Bei schwingender Beanspruchung ist die Methode der
Zahlverfahren geeignet. Sie wird in dem vorliegenden Buch
beschrieben und bewertet. Die Autoren bieten einen kompakten
Uberblick uber den Stand der Technik und liefern Empfehlungen fur
die Anwendung in der Praxis."
