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.
