Perform uniaxial fatigue analysis using S-N (stress-life) and E-N (strain-life) approaches for predicting the life
(number of loading cycles) of a structure under cyclical loading.
Perform multiaxial fatigue analysis using S-N (stress-life), E-N (strain-life), and Dang Van Criterion (Factor of
Safety) approaches for predicting the life (number of loading cycles) of a structure under cyclical loading.

Tip: Expand the width of the dialog to view a clearer picture of the
plot.
On the bottom half of the dialog, set the radio button to
Auto for event creation.
Select both the load 1 (block1) and load 2
(block1) channels and Subcase 1 and
Subcase 2, then click to create the first event.
In a similar manner, create a second event by selecting load 3
(block1), and load 4 (block1),
Subcase 1, and Subcase
2.
Activate the checkboxes for the two events.
Set the Scale as shown in the image below.

Optional: Enter a name for the run.
Click Run.
Result files are saved to the home directory and the
Run Status dialog opens.
Once the run is complete, click View Current
