Numerical and experimental verification of a new model for fatique life; Numerisk och experimentell kontroll av ny livslaengdsmodell

Technical Report:

Abstract

A new model for fatigue life prediction has been investigated in this report. The model is based on Palmgren-Miners rule in combination with level crossing. Data from literature and experimental data generated in this project have been compared with fatigue life prediction made with the new model. The data have also been compared with traditional fatigue life estimations base on the rain flow count method. The fatigue life predicted with the new model often agree better with actual life than predictions made with the RFC-method. This is especially pronounced when the loading sequence is very irregular. The new method is both fast and simple to use. (au).
