The following sections describe various pertinent program inputs which merit further elaboration.
•S-N Curve Data outlines the equations used for calculating S-N Curves.
•Scale Factor for Stress Computations describes how scale factors can be used to transform stress units so that they are consistent with S-N Curves.
•Threshold Thickness discusses the effect of threshold thickness on materials.
•Stress Properties describes how to apply effective geometric properties to element sets for use in calculating stresses.
