Material Library Specifies a materials library file, which defines the materials available to each
channel. The default is the RPC III materials library supplied with the Fatigue
process.
Damage Model Selects the damage model you will use for all fatigue processes.
RPC III provides both strain life and generic stress life damage models.
The Local Strain-life Approach (LSA) damage model selections include the
following:
• BASIC—strain-life approach to fatigue analysis (zero mean stress).
• MORROW—strain-life approach to fatigue analysis (mean stress
correction applied).
• SWT (Smith-Watson-Topper)—strain-life approach to fatigue analysis
(mean stress correction applied).
The Generic Stress Life (GSL) models include:
• GSL—generic stress life approach, no mean correction
• GSL_MEAN—generic stress life approach, mean correction
Note The selected damage model may influence the available materials.
Only materials that contain valid data for the selected damage model
will appear in the list shown in the Materials tab.
Default Number of
Bins Specifies the number of bins you will use for all new fatigue processes (the
default is 64).
Note If the default number of bins is changed, the value is also changed on
the Signals tab for all corresponding signals.
Default Material Specifies the material that will be the default for all new fatigue processes that
are created.
Note If the default material is changed, the value is also changed on the
Signals tab for all corresponding signals.
