Abstract
This project investigates the different methods used for determining the stress range used in fatigue calculations. The focus is to investigate the fatigue damage in welded connection. First, a global beam model was used to identify the governing load case before using ANSYS Workbench. Then, the fatigue damage was compared based on the stress range determine in the ANSYS Workbench model. This analysis aims to determine how the stress assessment has influenced the fatigue damage and the process used to determine the stress range by finite element. The stress ranges were then used to determine the fatigue damage based on the simplified fatigue assessment method by two-parameter Weibull distribution. The results provided hereby are also compared, finally argued, and the deviation between the outcome of the different approaches is debate.
