Fatigue
The General category allows you to change the default values in the Details view for the following:
Design Life: Number of cycles that indicate the design life for use in fatigue calculations. The default is 1e9.
Analysis Type: The default fatigue method for handling mean stress effects. The choices are:
SN - None (default)
SN - Goodman
SN - Soderberg
SN - Gerber
SN - Mean Stress Curves
The Goodman, Soderberg, and Gerber options use static material properties along with S-N data to account for any mean stress while Mean-Stress Curves use experimental fatigue data to account for mean stress.
The Cycle Counting category allows you to change the default values in the Details view for the following:
Bin Size: The bin size used for rainflow cycle counting. A value of 32 means to use a rainflow matrix of size 32 X 32. The default is 32. The range is from 10 to 200.
The Sensitivity category allows you to change the default values in the Details view for the following:
Lower Variation: The default value for the percentage of the lower bound that the base loading will be varied for the sensitivity analysis. The default is 50.
Upper Variation: The default value for the percentage of the upper bound that the base loading will be varied for the sensitivity analysis. The default is 150.
Number of Fill Points: The default number of points plotted on the sensitivity curve. The default is 25. The range is from 10 to 100.
Sensitivity For: The default fatigue result type for which sensitivity is found. The choices are:
Life (default)
Damage
Factor of Safety
