Einflußgrößen der Betriebsfestigkeit geschmiedeter Bauteile

For dimensioning purposes of components it is necessary to consider the relevant strength data, the properties of the material and the influence of the manufacturing process as well as the shape of the component. The type of the main factors producing stress under operating conditions is of decisive importance for the strength behaviour under operating conditions. Manufacturing and after treatment of the forged components have an important influence on the fatigue strength under vibratory stress. This paper provides a survey of these factors of influence and discusses their effect on the strength behaviour under operating conditions of forged components.
