摘要：

This paper deals with high cycle fatigue design methods for internal pressure loaded components of diesel injection systems. Intensive studies of material fatigue behaviour and the derivation of fatigue calculation methods in combination with adequate finite element calculations led to successful prediction methods. One interesting approach is the description of notch effects with volume integrals, which is outline in more detail.
