    Description / Table of Contents: The Gradient of the S, N-curve. The classical two-parameter basic equations of Wöhler and Basquin and also the four-parameter equation of Palmgren/Weibull approximate the Wöhler curve in certain ranges only. They fail in particular when one attempts to use them to convert a service life increase into the appropriate gain in strength. For a more exacting analysis these approximations must be replaced by models of the Wöhler curve which are nearer to actual reality.
    Notes: Die klassischen Zwei-Parameter-Ansätze von Wöhler und Basquin, aber auch der Vier-Parameter-Ansatz von Palmgren/Weibull approximieren die S, N-Kurve nur bereichsweise; vor allem versagen sie, wenn man sich ihrer bedienen will, um eine erzielte Lebensdauersteigerung in den entsprechenden Festigkeitsgewinn umzurechnen: Bei anspruchsvolleren Analysen müssen diese Approximationen durch wirklichkeitsnähere Modelle der Wöhlerkurve ersetzt werden.
