FREE ABSTRACT (to read the full article, please log in below).
FE-based fatigue analysis was applied to a plate-with-a-hole specimen and
a truck exhaust bracket to predict the critical location and fatigue life.
Commercial software packages were used for both finite element and fatigue
analysis. The objectives were to verify the quality of the virtual approach
to durability assessment and establish good practice in using such software
packages. The predictions from computer simulation and analysis were correlated
with laboratory test results. The issues relating to FE mesh quality and
its effect on the subsequent fatigue analysis was investigated. Different
methods of material elastic-plastic correction were used and the results
compared. This investigation has demonstrated the effect of each major input
to fatigue analysis software on the life prediction and some measures that
can help improve the correlation between the predicted and the tested fatigue
