Original abstract
The presented paper introduces an approach for fatigue lifetime predictions of notched round bar specimens made of HDPE. This approach uses axial stress distribution calculated from finite element analysis and experimental fatigue data. The fatigue results obtained experimentally on the round bar specimens with “v” notch with radius R = 0.4 mm and extremely sharp notch are used for a determination of averaging distance. The averaging distance is applied to specimen with different notch radius for determination of its fatigue lifetime. The fatigue lifetime prediction of a specimen with notch radius R = 0.1 mm is performed. Tese fatigue lifetime predictions are compared to experimental fatigue data.
